Gainaxing



""It's like living inside a bouncy castle!""

- Cassandra!Rose (New Earth), Doctor Who

The act of drawing a female character with unusually large and buoyant breasts and without a bra, then animating every individual jiggle, sway, bounce and bobble they undergo. Also known as Gainax Bounce or the Gainax Bounce Effect.

The motion so displayed is typically asynchronous—each breast is animated separately and possesses its own individual movement.

The term was coined by fans some time before 1993 and makes reference to the anime production Studio Gainax, many of whose earlier releases made use of this particular variety of Fan Service. According to a Usenet post from 1993, one particular busty young woman from the Gainax anime Otaku no Video inspired a tongue-in-cheek unit of measurement for Gainaxing one full bounce is apparently equal to one "Misty May".

For the live action TV version, see Jiggle Show.

For real-time generation of jiggling movement in videogames see Jiggle Physics.

When a male does it, it's a Pec Flex.

The Trope Maker

 * The very first Gainax Bounce appeared at approximately 3 minutes and 20 seconds into the legendary Daicon IV opening animation, created in 1983 by the group of fans who would then go on to become Studio Gainax. See Wikipedia or this video for more info on the Daicon openings.

Advertising

 * Bizarrely, advertisements for the UK insurance comparison website "Confused.com" seem to show this very often, such as in this advert. And this one. Oh, and this one. Whoops, almost forgot this one. And yes, they do get weirder and more overt each time.

Anime and Manga
"Kyon: Too many beach balls!"
 * The whole trope can pretty much be summarized by 300 boobs in 2 minutes, in this gloriously NSFW AMV. And here you can download the original from animemusicvideos.org.
 * Parodied in Jungle wa Itsumo Hale Nochi Guu/Hare+Guu in which Gupta thinks back to an anime he saw. see for yourself(NSFW).
 * Plentiful in Gravion (which provides this page's picture), especially with Mizuki Tachibana, who bounces considerably with the slightest movement, even swallowing.
 * Gainaxing is a signature of Gravion's creator, Masami Obari, present in his works, including the Fatal Fury anime adaptions and Voltage Fighter Gowcaizer, in which it's put to the utmost extreme.
 * Cowboy Bebop has the character Faye Valentine, who is breathtakingly beautiful with gigantic pneumatic breasts that seem to have minds of their own. She also almost invariably dresses in a manner that would, in any American city in the late 20th Century, cause everyone who saw her to conclude immediately that she is a streetwalker. Canon indicates that she does this on purpose to distract men. On one occasion, she wears a perfectly normal evening gown.
 * The seventh One Piece movie had the girls bounce from doing absolutely anything. Hell, in a few scenes, Nami will simply be standing around, perfectly still, and her boobs will just randomly bounce quite forcefully all on their own. See for yourself.
 * Used again slightly more subtly during the Spa Island Filler Arc. Also Chick Ivankoff. In the latter case, wheter it's Fan Service or not is up to you.
 * Used later in the Marineford Arc with scenes of Hancock's boobs bouncing every time she moved around. Here's an example
 * Also used in the tenth One Piece movie when Nami runs down some stairs.
 * Of course, this actually does happen if you run down stairs incautiously, especially without a really good bra. And it hurts a lot.
 * Gunbuster (called "Bustgunner" by some fans) and Otaku no Video from Gainax are the two productions which allegedly inspired the term.
 * Perhaps ironically, Gunbuster actually features what can be considered as close to realistic as possible physics for the bouncing breasts. Noriko's bounced so much mainly because she moved around a lot even when she wasn't wearing a bra.
 * Just about any female character in the various Burn Up animes.
 * Mune-mune in Gainax's Abenobashi Mahou Shoutengai is a deliberate parody—right down to her name, which actually translates as "Tits-Tits".
 * And she's the main character's
 * Kurono Kurumu in Rosario + Vampire. The movement of her breasts even produces audible sounds! And in episode 4, Kurumu's fat stalker (or rather, his belly).
 * Chapter 95 of the manga Mx0 plays this trope for satire with a magical liquid that makes some (already extremely buxom) girls' breasts experience only 1/6 normal gravity. The result is a lot of bouncing, first from falling, then from wind, then an earthquake.
 * To LOVE-Ru seems overly fond of this. Espically Lala. Just watch the OVA opening, 1 minute and 30 seconds of pure bounce.
 * Every female character that appears in the various Ranma ½ motion pictures—even the ones who are supposed to be small-breasted. This contrasts with the main series where they never seem to move at all, since the show is kind of old and didn't have a huge budget.
 * Especially since the characters are considerably less endowed in the television series.
 * The sheer quantity of gainaxing found in the anime Plastic Little inspired ADV, the North American distributor/dub house, to include an on-screen "Jiggle Count" meter as one of the special features in their DVD release.
 * The anime Shinkon Gattai Godannar takes Gainaxing to the extreme, since even the mecha have breasts (and in one particular case, both the mecha and the pilot have humongous jiggling breasts). The only exception to this is Lou, the show's Token Mini-Moe.
 * Taeko and a few others in Ai Yori Aoshi.
 * Practically every female role in Divergence Eve and its follow-up. It may be noted that outside of this and the fanservicey opener and closer, the series is remarkably serious in tone and tells its story in blissful.
 * Caldina in Magic Knight Rayearth.
 * Virtually any adult female in Devil Hunter Yohko
 * The opening credits of Landlock.
 * The title character in Amazing Nurse Nanako falls prey to this, making an otherwise well plotted series difficult to watch ""
 * While not exactly as flagrant, Murrue Ramius of Gundam Seed has the dubious honor of having her bouncing chest be one of the few whose bouncing was actually animated and used as Stock Footage every time the Archangel took a particularly nasty hit in battle. This seemed to be limited to her, until first officer Natarle Badguirel ended up in command of her own ship, whereupon she gained the suddenly bouncing breasts (albeit not as dramatically given her modest proportions), as did Flay Alster as part of her crew. Whether this is actually an accurate depiction of how breasts move in zero gravity is debatable.
 * Murrue was also the first woman in the Gundam franchise to have her jiggle in the opening credits of the actual series itself. She was replaced in the HD Remaster by Fllay Alster. The James Bond opening credits level nudity is also bra-less and even had male viewers often going "...those don't work that way." Female tropers, on the other hand, winced in pain and often skipped those credits.
 * "They wounded the burst-proof battleship in order to sway the heart of the captain." - Moetan II, volume 1 (the book). Obviously, the word "heart" in the Japanese translation can also mean "breasts".
 * Fllay also displayed quite a big of bounce in the flashbacks to the sex scene with Kira
 * Yoko, and Kittan's three sisters (who come in small, medium and large for your viewing pleasure) in Tengen Toppa Gurren Lagann. Guess who it's made by. In fact, the English trailer for Gurren Lagann contained the words "that famous Gainax bounce". Yoko is an especially amusing example because her breasts seem to spontaneously Gainax without any movement on her part, whenever any attention is called to them.
 * Mikuru Asahina, the Moe character in The Melancholy Of Haruhi Suzumiya, displays Gainaxing, particularly in the opening credits.


 * Also very evident in the ending credits, especially at 0:13-0:16 (she's on the right).
 * It's even Lampshaded in a Season 2 dub outtake: "Look at these things, they move independently of each other!"
 * Rushuna Tendo, every episode of Grenadier. However, as she keeps her ammo in her cleavage, this is actually somewhat practical. The Big Bad Setsuna, being similarly well-endowed and trained, does the same thing.
 * And for extra Gainaxing, she uses her bounce to execute an Unorthodox Reload, which always gets plenty of Male Gaze.
 * The AMV "The Fanservice Video: Bouncing Back For More" by Zarxrax is dedicated to this effect.
 * Almost every female character in the anime Girls Bravo.
 * Naga the White Serpent, from The Slayers.
 * It almost got her killed once, her rack sprang back into shape after being pressed against a wall, nearly launching her over a cliff.
 * Angela, an American visitor to Genshiken, displays this conspicuously (complete with bouncing sound effects) to make the differences between Japan and America (or at least Eagle Land) more obvious, and to highlight her more upfront attitudes about sex (she is an unashamed Yaoi Fangirl) and maybe a bisexual (she was at least interested in the male oriented hentai as well).
 * Oono also gets this quite often.
 * A certain animation team in the rotation for Digimon Savers used this technique on Rosemon, and it's probably not a coincidence that they animated BioLotusmon's only appearance.
 * It's worth noting that before Savers, the only minor use of this trope was in the second Tamers movie—Sakuyamon's bounce a bit when she's freed from a Parasimon tentacle.
 * Siesta from Zero no Tsukaima, pictured [[media:cit zero no tsukaima 2 behold the power of siesta.gif|here]]. You're probably not looking at the Love Bubbles surrounding her.
 * Not to mention Kirche the Ardent.
 * Siesta is nothing compared to Tiffania, who barely has to move to set her breasts bouncing around like Flubber.
 * Used to great hilarity in one episode when the gang is trapped in a cave. They hear something approaching fast and prepare for a fight, until Saito realizes exactly what that sound is with a priceless look on his face while the viewers get the obligatory chest shot of the approaching Siesta (who's wearing the Sailor Fuku outfit Saito bought earlier).
 * Mai from My-HiME dresses conservatively, but her somewhat large (but not Gag Boobs-level) chest still has a bit of bounce to it. A scene early in the anime replicated during an argument with Yuuichi and Shiho gives them an audible "boing". According to supplemental materials, it's not even Mai who has the largest bustline. She's beaten out ever-so-slightly by Haruka, who doesn't have a whole lot of bounce, but still looks good in a swimsuit.
 * Macross Frontier features a whole raft of characters with sufficiently Gainaxed breasts, including Sheryl and the Miss Macross Frontier contestants (which makes Ranka uncomfortable.) Also, zero gravity bouncing. Very unique.
 * Interestingly the show also subverts the trope slightly: when a fully sized, thirty-foot-tall Zentraedi, Klan Klein has a rather terrifying bust that may actually be capable of killing a normal-sized human. Micronized, however, she doesn't possess anything that can be Gainaxed.
 * R.O.D. TV had one particularly infamous chase sequence where Nenene finally finds her long lost friend (love?) Yomiko Readman. Yomiko runs away and Nenene gives chase. As they sprint, their bosoms (which had been largely still until then) bounce and sway like jello earthquakes. It's also worth noting that Yomiko's bustline went from a mild C-Cup in the OVA well into DD territory for the TV series, set several years later. A late blooming?
 * It isn't just the chase scene. Watch Nenene's bosom in the first episode. They ripple like water.
 * This happens to Milly and Shirley during one of the School Festival activity episodes in Code Geass and to Kallen, the most noticeable example being her encounter with Suzaku on Kamine Island. You'd think that Kallen, having one of the larger chests of the female characters featured on the show as well as being the most physical girl, would get a lot more of this during the action sequences but the total count reaches no more than a handful.
 * Well, any more than a handful is a waste.
 * After the Time Skip in Magical Girl Lyrical Nanoha, Nanoha and Fate, no longer young girls, displayed this trope during their Transformation Sequence, as did Subaru.
 * Before the Time Skip, Arf displayed this trope whenever she got a chance to.
 * Surprisingly, several girls in the Saiyuki anime jiggle around in action, even though the show is mostly fangirl fodder.
 * Then again, Saiyuki was originally marketed as Shonen.
 * Done poorly with Bekira in Wagaya no Oinari-sama.. Kind of Lampshaded by Noboru taking a quick glance at Kou's assets for comparison. Subverted later on when it turns out those weren't actually her breasts.
 * Parodied and lampshaded in an anime-original RPG Episode of Hayate the Combat Butler where the bouncing boobs of the RPG game's boss is focused on constantly and has a sound so audible a character points out that she hears the sound of the bouncing from a considerable distance away.
 * In Akane-Iro ni Somaru Saka's eighth episode, whenever the camera focuses on Tsukasa, her breasts appear to take on a life of their own. The first scene, which is just a profile shot of her laughing, has them bouncing up and down like crazy.
 * In one episode of Naruto, the seriousness of Gaara transforming is lost thanks to Temari's inexplicable Gainaxing, which is something that no character in the show had really shown before or since (even Tsunade, who despite having a bustline greater than a meter, no bra, and a very active combat style, has her breasts remain perfectly stable).
 * It appears as though you haven't seen 106 cm (bad quality)
 * Now Samui from the Cloud village has it
 * Eiken has a ridiculous amount of Gainaxing happening in almost every scene. Chief among the guilty are Kirika and Token Mini-Moe Komoe, who quite literally bounces part of the opening credits on her chest.
 * Margery Daw in Shakugan no Shana's Festival Episode.
 * Junko Asagiri from Desert Punk, during the end credits.
 * And, you know, everywhere else.
 * Rosette does this in the third episode of Chrono Crusade—unfortunately bad animation makes it look as if she had bags filled with water instead of breasts.
 * Done with refreshing realism in Gargoyle of the Yoshinagas. A character's breasts do bounce but only after another character steals her bra.
 * Yurika in Akikan actually uses Gainaxing as a strategy. In a baseball game with Yell (who's distracted by moving objects), she apparently plays without a bra on purpose, leading to very springy bouncing that Yell just can't take her eyes off of.
 * Izumi in Kemeko Deluxe!, all the time.
 * Studio Gainax is responsible for animating the most recent Re: Cutie Honey OVAs. Hoo boy, is there ever Gainaxing in that show.
 * Ninin ga Shinobuden gives Shinobu a few good bounces in episode 4. Then again, the first half of the episode is a spoof of Fan Service anyway.
 * The baseball episode has a ninja distracting himself by imagining Kaede in a tiny bikini, complete with bouncing. The real Kaede bowls him over because he's not paying attention.
 * Parodied in Samurai Champloo when small-chested Fuu decides to carry a couple of cherry bombs by sticking them down the front of her kimono. And then she goes for a run. The result is quite comical, which is compounded by the occasional viewer who didn't notice the cherry bomb thing and thinks that her breasts have just gone insane.
 * The appropriately-named Bouncy Tiff, who is created to the real Tiff's dismay. She is drawn like a stereotypical magical girl and... err, deserves the "bouncy" portion of her name. Even the youngest character in the crew knows to cover his eyes. The anime she appears in? Kirby: Right Back at Ya!.
 * Miyuki in Basquash, who has her bouncing breasts take up the entire screen for a good few seconds.
 * Which is taken to the next level with Haruka Gracia, who we get to see jiggle on three separate occasions before actually seeing her face.
 * Check the Beach Episode of Please Teacher.
 * In the Makai Senki Disgaea anime, we have Jennifer, the female assistant of Captain Gordon, Defender of Earth!. The sight of her chest bouncing is enough to make Laharl sick.
 * Team coach Momoe from Ookiku Furikabutte.
 * Green Green, to a truly ridiculous extent.
 * In the same vein as Mikuru and Suzumiya Haruhi above, Kyou Fujibayashi of Clannad Gainaxes like mad in the opening credits of the first season, while bouncing a basketball.
 * Kotomi also does so in the Baseball Episode.
 * Also on the same vein, Patricia Martin displays it during while cheerleading in the opening Dancing Theme.
 * The SHUFFLE! OVA had Sia and Asa Gainax within the first three minutes. Then when Sia's dad replaces the water in the pool with eels, Nerine does as well.
 * The anime of Umineko no Naku Koro ni gave most of the women and girls a bad tendency to do this, which would be fine if this were a comedy series. Unfortunately, Umineko is not a comedy series. Poor Shannon has the worst of it. Every time she makes a sudden movement or reacts to something, her boobs also react, with a single bounce.
 * In Bleach, Rangiku's breasts bounce when she is frightened by Capt. Hitsugaya's intrusion. She even says that they almost popped out of her robe.
 * When Orihime was about to change (in front of Uryu, uncaringly), her breasts just flopped down from her shirt. In the video games, she demonstrates this as well.
 * Cirucci Thunderwitch has a blink-and-you-missed-it one in an Omake.
 * Even one of the more serene shows, Umi Monogatari, gets a chance to indulge in this trope. Oshima, Kanon's rival, is flaunting her own bust size, when Marin comes running up to greet her. Marin, already halfway to being an Innocent Fanservice Girl, is not wearing a bra. The results leave Oshima stunned.
 * Nodoka of Saki says hi. Just the simple act of walking could get her breasts jiggling.
 * A critic from Anime News Network once noticed that her entire wardrobe is sewn in just the right way for her shirts to perfectly cup her chest.
 * This happens in episode 19 of Fullmetal Alchemist: Brotherhood; for unexplainable reasons beyond pointing out that Havoc likes big boobs, Lust's boobs bounce considerably.
 * Mii in Jungle de Ikou! Gainaxes quite a bit, thanks in part to her huge rack (Mii's breasts are supposed to represent Earth's life-giving energy); this is taken to a somewhat absurd level when Mii uses her powers to turn into a giant.
 * Highschool of the Dead combines Gainaxing with Bullet Time. And it is ridiculously awesome!
 * Another Studio Gainax creation, Neon Genesis Evangelion, would always promise "more fanservice" in the next episode. Strangely, this was the one time Studio Gainax didn't follow this trope: the show did have a fair amount of tongue-in-cheek fanservice, but its overall animation style was less "cartoony" and trying to be photo-realistic, so unrealistic "breasts bouncing around like water balloons" didn't really happen that often.
 * They made up for it in Rebuild, when Mari puts on her new plugsuit and comments how comfortable it is, demonstrating how well it can support her relatively huge chest. It was relatively realistic, tough. And she was wearing skin-tight, elastic clothing at that time.
 * Also seen at two moments later in the movie, when destruction of the bones guarding an angel's core caused its chest to lose its tautness, resulting in a bounce of building-sized breasts; and when a naked Rei gasped in surprise.
 * In an odd variant, Brave Command Dagwon has this happen to Galaxy Luna's buttocks during her henshin sequence. (Said sequence starts at 1:07).
 * When Ukraine from Axis Powers Hetalia was featured in episode 42 of the webcast, her Gag Boobs received, well, quite the attention. And her shirt's front button popped out (followed by a later scene where she tries to sew the button back in place). And her boobs make an audible bouncing noise when she moves (which Latvia refers to as "booby bounce" in the English dub).
 * There's even a (NSFW, obviously) community dedicated entirely to her breasts.
 * And another!
 * Done in the manga of Mahou Sensei Negima through use of a sound effect. The sound of a bouncing breast is, strangely,.
 * Bouquet in the Blue Dragon series. Combined with Ms. Fanservice, as her powers only activate when she's naked.
 * Kasuga from Sengoku Basara series (anime) not only gets bigger boobs than in the game, but they visibly bounce around when she moves quickly. Seeing her status as Ms. Fanservice, it's not surprising.
 * Ghost in the Shell: Stand Alone Complex. The first view we have of the Hospital Hottie who has come to give Major Kusanagi a new cyborg body is her bouncing breasts. The fanservice is increased tenfold when she starts making Les Yay comments while examining the Bi the Way Major.
 * Notably averted with the Major herself, however, whose admittedly generous breasts are artificial, like the rest of her body, and actually animated that way.
 * Higurashi no Naku Koro ni had this happening to Mion . Like every other Fan Service trope used, it came off as seriously creepy.
 * Ladies versus Butlers! is full of this, having ample fanservice moments. Sernia Iori Flameheart in particular, she even gets the sound effects, generally the other girls don't.
 * Golden Boy did this quite a bit, especially in the first episode (from the owner of a computer software company).
 * Queen's Blade has this by the truckloads but episode nine of the first season is most appropriate example being a Cattleya centric episode
 * Airmaster Mina has plenty of this but she's a Subversion of Ms. Fanservice and her figure is played mostly for laughs as her breasts tend to bounce out of sync with the rest of her body and the movements are extremely exaggerated
 * Chu's entire entourage in Mouse, even the flat chested one.
 * Done hilariously in the Beach Episode of Tokimeki Memorial Only Love with swimming team captain Koayu Utsumi, whose Gag Boobs jiggle just from her merely looking around, complete with sound effects (and it doesn't help that it's getting all the attention of all the guys around, which she hates so much, and especially since she's on lifeguard duty at the time).
 * Happens at one time or another to most of the female cast of the anime releases of the Koihime Musou franchise who have large breasts, especially to Kannu. Ryuubi even gets to do it on purpose later in the series to lure someone into a trap.
 * The entire point of Training with Hinako.
 * Haruhara Haruko in FLCL. It is Gainax after all. Of particular note is the random bunny suit she wears during the big battle in episode 5.
 * The eponymous Rio from Rio -Rainbow Gate!- has very bouncy assets, which get ample emphasis in the show. The fact that she dresses in an extremely revealing manner for a casino croupier, baring her midriff and wearing an ultra-short skirt, only exacerbates this.
 * Played for Laughs in Seitokai Yakuindomo with Aria Ichijou. Being Ms. Fanservice, her boobs jiggle on occasion, often to emphasize how jealous the other girls are of her size. At one poimt, she willed them to bounce on their own when the discussion turned to them.
 * Played for Laughs in the animated omake of Black Lagoon, when Rock wakes up as a woman... "WITH HUGE BOOBS!".
 * In the series proper, Revy's very acrobatic Gun Fu causes this to occur during her fight scenes. More noticeable in some than others.
 * Maicchingu Machiko Sensei was perhaps the first anime to do this, although the gainaxing in that show is tame by today's standards.
 * Happens a bit in the Fairy Tail anime with the various girls, most notably.
 * Seraphim often from Kore wa Zombie Desu ka?
 * Zigzagged between Takane and Azusa in the anime version of THE iDOLM@STER
 * In chapter 117 of Black Cat, one panel has Saya Minatsuki dodging Creed's slashes, causing her breasts to swing in visibly different directions. She's far from the bounciest female in the series, but she does seem like the kind of girl that would go without a bra in the comfort of her own home (which is where she was when that asshole Creed barged in on her).
 * Maji De Watashi Ni Koi Shinasai has Momoyo, whose Boobs of Steel defy gravity.
 * Kurokami Medaka has this all the time in the Animated Adaptation of Medaka Box. Complete with the bouncy sound effect. Well, it is a Studio Gainax anime...
 * Seikon no Qwaser and Manyuu Hikencho, takes this trope Up to Eleven.
 * Sekirei is a World of Buxom Harem Genre anime/manga that has the tagline Boobies for the win! and the nickname "Pokémon with tits". You do the math.
 * Rin in the BAKUON!! anime can't seem to make a moment small enough to avoid Gainaxing.
 * Rail Wars!: From the training montage in episode 1, it appears that Koumi has never heard of a sports bra. (When a video clip of her jiggling was posted to Danbooru, the comments were along the lines of "that looks painful".)

Eastern Animation

 * Aachi and Ssipak has a female character that does this throughout the movie to hilarious effect. At one point, she somehow manages to find herself strapped to a motorcycle, riding on her rack, while bouncing down some stairs.

Film

 * A truly groan-worthy live action example in Transformers: Revenge of the Fallen, in which Mikaela (played by Megan Fox) bounces like Pamela Anderson on Baywatch in Michael Bay slow-motion in what is supposed to be a dead-serious escape sequence. However, given that the entire sequence is in slow motion, she is running for her life, and they only had one take, it's somewhat more understandable.
 * A rather disturbing one is present in Despicable Me, near the start. as  causes an old woman's saggy...well, you get the picture.
 * The Z-grade film Hollywood Hot Tubs had Crystal, whose entire reason for existence was jogging braless in every scene, even jogging in place when standing still.
 * A similar film, Bikini Summer, showed an extreme close-up of jiggling before the opening credits even began rolling.
 * Black Mama White Mama, every time Pam Grier (or many of the other nameless women) run.
 * One of the Tomb Raider movies had a particularly glaring example even for them, where Lara runs (in slow motion of course) at full pelt resulting in a lot of movement that looked like it would be quite painful really.
 * That would be the first one. It looks like it ought to violate the laws of physics and biology, probably a result of the decision to enhance Angelina Jolie's breasts.
 * Word of God states that the only part of Angelina Jolie that actually had any padding at all while filming was her breasts.
 * In the Uwe Boll film House of the Dead, Ona Grauer becomes outright pneumatic during a slow motion run during an explosion. Like Jell-O on springs, indeed.
 * There are a couple of noteworthy sex scenes in Cabin Fever featuring Cerina Vincent's magnificent milkmakers. But in particular, the second one involves a behind-the-back shot in which we can see an intense jiggle as she forcefully rides her lover du jour.
 * In The Legend of Zorro, there's a scene where Catherine Zeta-Jones runs away from dogs in a low-cut dress. It's probably not intentional, given the shortness of the scene.
 * In the Adam Sandler movie Click, one of the uses Sandler's character finds for a remote control that works on the real world is to use the "slow" function on a buxom jogger.
 * Becky (Rosario Dawson) dancing on the roof of Mooby's in Clerks II. That is all.
 * There's a less, uh, restrained example of her in Alexander.
 * Animalympics: one of Brenda Springer's scenes really could've ended slightly earlier than it did, but the animators apparently felt the shot wouldn't feel complete until all the jiggling stopped.
 * Another particularly cringe-inducing example is when Caramon first realizes that Tika is a beautiful woman in the amazingly wonderful Dragonlance film.
 * Surprisingly, there's a bit of Gainaxing in the live-action Speed Racer movie. No, seriously, take a look at Trixie (Christina Ricci) when she runs into the room during the ninja fight scene.
 * Parodied in the Leslie Nielsen film Wrongfully Accused—while the female lifeguards are running in slow motion, their breasts make comically audible bouncing sounds.
 * Airplane! has a shot where we have a closeup on a wobbling jello plate while the plane is in turbulence, and then pans over to... well, just guess.
 * Also, the scene where the passengers panic after the line "Does anyone know how to fly a plane?" has a topless woman appearing out of nowhere, jumping around close to the camera.
 * G.I. Joe: The Rise of Cobra has a scene where the team is exercising in their gym, and Scarlett (Rachel Nichols) just happens to be jogging on a treadmill.
 * Both Miss Scarlett and Yvette do this in Clue.
 * Star Wars A New Hope of all places. Suffice to say they eventually had to tape down Carrie Fisher.
 * Eliza Dushku has had this in many of her roles, but special mention must go to her first topless scene in The Alphabet Killer.
 * Epic Movie does this with three different jogging people:
 * The first one is a scantily-clad woman.
 * The second one is a shirtless man whose Gag Penis bounces.
 * And in a moment of Fan Disservice, the third one is a fat hairy shirtless man with bouncing man-boobs.
 * Probably the most horrifyingly disgusting instance of this is in the 2000 sequel to the Eddie Murphy remake of The Nutty Professor, with Granny Klump.

Literature

 * Lois McMaster Bujold's Diplomatic Immunity mentions the 'charming effect' zero-G has on the female form.
 * In Arthur C. Clarke's Rendezvous With Rama, Commander Norton notes how distracting women can be in zero-gravity, particularly if "sympathetic vibrations" occur.
 * There is an interesting description of this happeneing to Big Boobied-Bertha in one of the How to Train Your Dragon books.

Live-Action TV

 * 'Allo 'Allo!—let's just say "vibrating ice cream truck".
 * Elaine on Ally McBeal invented a vibrating bra that would make the wearer's breasts twirl in circles.
 * The Bill—a couple of incidents described as "Bouncy Bouncy Jo Masters".
 * BBC Garden-show hostess Charlie Dimmock received a certain degree of fame for her tendency to go braless and jiggle.
 * So, forty years ago, did children's TV host Susan Stranks. Fetish Fuel for the under-fifteen set, anybody?
 * This video. So much bouncing, and no shirt! NSFW. http://www.youtube.com/watch?v=wTs96p88pcc&feature=channel
 * There is also here from the same show.
 * Baywatch. Kind of a given, what with the cast containing so many gorgeous women in form-fitting swimsuits.
 * Referenced in Friends: "See, this is the brilliance of the show. I say always keep them running. All the time, running. Run. Run Yasmine, run like the wind."
 * There's a memorable (read: hot) scene in the second paintball episode of Community which shows Annie running in slow motion. Bounce, bounce, bounce... ah...
 * Long before Pam Anderson hit the beach, Lynda Carter perfected the art of running in slow-motion in a bustier in the 70s Wonder Woman TV series. There is a reason why some say "the Baywatch run" was invented by this series. Observe
 * The Price Is Right. Seriously. Don't believe me? Watch this.
 * Elliot from Scrubs is pretty much the show's Ms. Fanservice, and it often happens because she can be neurotic and excitable. A particularly notable one is when they are in a bar with J.D. and Turk playing a game, Elliot wants to play along too, saying "Oh... Do me! Do me!" while jumping up and down.
 * Also after her makeover in "My All American Girl", walking down the hallway... bounce... bounce...
 * Kelly Bundy from Married... with Children often did this whenever she got excited.
 * Actually, most of the women (who weren't flat-chested like Marcy or fat like the many customers in Al's shoe store) on Married... with Children gainaxed, from Peggy Bundy to the many shallow love interests Bud tried to score with.
 * My Name Is Earl had Catalina's stripper act entirely just jumping up and down. Another episode featured a claymation Joy whose breasts moved independently of each other, much to Randy's fascination.
 * This also often happened to Chrissy Snow from Three's Company whenever she got excited, resulting in the coinage of the term "Jiggle Show".
 * Ghost Whisperer has taken numerous opportunities to have Jennifer Love Hewitt run in something low-cut. In fact she seems to find a way to introduce some jiggle to every project she's in, including the bra ads.
 * Rachel Luttrell as Tayla Emmagan in Stargate Atlantis used to be known for this. Even in fight scenes. Especially in fight scenes! One director had her stop swinging a staff and * pose* in order to display her impressive chest to best effect.
 * Nissan car commercial
 * A Whose Line Is It Anyway? rendition of "News Flash" resulted in, well... Here you go.
 * Despite having the page quote, Doctor Who is not an example, partly because it's live-action, and that would be impossible anyway. The line comes from when the character Cassandra, who'd been a flap of skin for the last few-hundred years, possesses Rose, and is rather enjoying her....assets. To be fair, she did the exact same thing when in the Doctor's body.

 * Any Sabrina Salerno music video.
 * Make My Boobies One More size
 * Bastian - You've got my love. Yes. Yes I do.
 * Leather Hands - Vertical Lines.
 * Meg White in, well, pretty much any video where she's seen drumming.
 * A brief but very conspicuous scene in this video of a live performance of Earth Wind and Fire's song "September", after about 1 minute 35 seconds in. It's impossible to miss, and is an utterly hilarious Non Sequitur Scene.
 * Catherine Wheel's "Eat My Dust You Insensitive Fuck".

Stand Up Comedy
"I said, ‘I’d like to do a show where I rid the world of all the fevered egos that are tainting our collective unconscious,’ and the guy at CBS said, ‘Will there be titty?’ And I said, ‘Sure, I dunno, sure.’ BOOM! A check falls in my lap and... I'm a producer. I never knew it was that easy. All this time I've been trying to write scripts and characters and plots and stories that had meaning... “Will there be titty?’ ‘Sure.’ Boom, I'm a producer now. ‘Where have you been all your life boy, we've been looking for you in Hollywood. What’re these titties gonna do?’ ‘Uh… jiggle?’ BOOM! Another check falls in my lap. ‘You’re a fuckin’ genius. Give him another check. I can’t write enough checks for you. You’ve answered our prayers in Hollywood. Jigglin’ titties! Who woulda thunk of it?’"
 * Parodied by Bill Hicks on his Rant in E-Minor album:

Video Games

 * In Ninja Gaiden Sigma 2 for the Play Station 3, the Gainaxing of all female characters is controlled by the motion sensor in the controller. Lampshaded hilariously in the commercial.
 * In Vampire:The Masquerade-Bloodlines many female Vampires, noticably Jeanette and VV have jiggle animations.
 * Banjo Tooie has Mrs. Boggy, an obese polar bear who jumps up and down for no discernable reason.
 * Watch Morwen in Lord of the Rings: The Third Age when she starts to walk around in the cutscene after you rescue her. Somebody on the animation team was inconsistent.
 * Rayne, the main character of the BloodRayne series of games, and most of the other female characters in it, was notorious for it and noted by the media several times for its 'realistic' breast physics.
 * Though Rayne's breasts are immobile while speaking except for the first half second of every line when they bounce exaggeratedly.
 * Mai Shiranui from the Fatal Fury and King of Fighters series. The Fatal Fury anime movie, in particular, was infamous for the animators actually showing (very, very briefly) the inevitable wardrobe malfunctions her Gainaxing would cause in her distinctive costume during fight scenes. Viz Video, who released Fatal Fury in the U.S., used to show her bouncing in the trailers while the narrator made enthusiastic reference to "dual-independent-suspension ninja girl Mai Shiranui". Although her design in the first few games was relatively more conservative, the anime (and the 2D Jiggle Physics in the King of Fighters videogames) resulted in her Flanderization into a walking incarnation of this trope. In fact, the latest incarnation of the King of Fighters takes this to Serial Escalation levels.
 * Soul Calibur III's shop girls, specifically what could be done by repeatedly hitting Triangle in their shops. Especially Valeria's.
 * Giving Xiangua's style to a well endowed custom character in Soul Calibur IV will result in lots of bouncing
 * Quite noticeable in Soul Caliber Legends, namely Ivy. Every movement made them bounce with really weird physics, including going in and out(...?)
 * If any character is the Soul Calibur shining example of jiggle physics, it's definitely Taki.
 * Rouge the Bat, from the Sonic the Hedgehog series, often has boobs that bounce a lot.
 * In Sonic Adventure 2, go to a level with Rouge. Face the camera. Jump. Jump again.
 * Hilariously, the exact same motion engine is applied to her ears. They keep time with her tits perfectly.
 * Dead or Alive Xtreme Beach Volleyball. The breast movements were synchronous until Dead or Alive Xtreme 2, when they consequently lost any resemblance to actual bosoms.
 * The first game even gave the option of choosing between static, semi-normal, and downright comical Jiggle Physics.
 * Tomb Raider's main character, Lara Croft, gets pretty jiggly.
 * Especially in the sixth game in the series, The Angel of Darkness.
 * Take a look at Isabela walking from the side in Dragon Age 2.
 * Castlevania Judgement has Carmilla's do this, and Sypha, even Shanoa's a little bit, but she's more known for her Sexy Backless Outfit.
 * Super Robot Wars, despite being a video game where all the action is done by Giant Robots, has rather extensive bouncing in the anime-ish cut-in pictures. Very prevalent in the Alpha series, where you can expect any original female character to have Gainaxing bounce, unless her name is Ibis Douglas. This also gets carried over to the latter handheld SRW games, such as J and W. (Un)fortunately, Super Robot Wars Original Generation somewhat mellowed or stopped this practice.
 * Only for Endless Frontier to bring it back in a grand fashion: 3 of the playable characters happily show off their bosom every time you perform their Limit Break (two of them involving a mechanism specifically designed to remove the cloth covering their cleavage), and most female bosses are happy to do this as well.
 * Funnily enough, even Xiaomu, from Namco X Capcom has what little cleavage she has bounce. In fact, every female character with the exception of Suzuka and Kyon Feulion have bouncy breasts.
 * It starts at Alpha 2 and Alpha 3 had the most extreme version of this (I'm looking at you Selena Recital). After that, the bounce is a bit more in line with realism. By Z, the bounce is fairly tame and looks fairly natural (which is impressive given Xine's impressive rack).
 * In fact, there's a fan-made montage of these cutins in Super Robot Wars Z2: Saisei-Hen, set to DYNAMITE EXPLOSION
 * Tales of Symphonia played with this with the well-endowed (but not shockingly so) female ninja Sheena. However, it's only most noticeable when using her as the party avatar walking around, and it's hard to spot normally (there are a couple of places where you can get a closer look and have her run in place). It's also present in the animated ending cutscreen on, the credits credit Gainax themselves for said animation.
 * Queen Valentina from the original Super Mario RPG had a conspicuously long after-hit animation that consisted solely of her flinching and jiggling for a few seconds.
 * It's notable that the jiggling part lasts about 3 times longer than the flinch.
 * April May in Phoenix Wright: Ace Attorney shook her stuff when flirting or when she got extremely pissed off.
 * And then there's the hilarious hentai game Phoenix Drive, in which female characters' breasts spontaneously Gainax every few seconds, much as humans' eyes spontaneously blink.
 * Jessica from Dragon Quest VIII, to the point where she distracts from the action taking place on screen whether you like it or not.
 * Lucia and Sheena, the unlockable characters of Contra 4. That is, if you look closely at their sprites.
 * Lyn, from Fire Emblem: The Blazing Sword, every time she attacks while wielding her end game weapon.
 * In Metal Gear Solid 4,
 * No mention of Metal Gear's PSP Spin-Off Metal Gear Ac!d 2? They even gave you 3D goggles for it.
 * The Tekken spinoff 'Death By Degrees'' has "breast physics" as its (only) selling point (along with Clothing Damage in boss fights).
 * In Skies of Arcadia, Belle, one of the crew members you can recruit, is rather bouncy. Especially since she's also a Genki Girl and source of much Innocent Fanservice. Did we mention you can end up talking to her while she's polishing an artillery shell?
 * Fiona from Haunting Ground suffers this. Especially noticeable when you unlock some of her other very revealing outfits.
 * Nearly every female character that isn't flat chested in Disgaea.
 * Marjoly in Rhapsody: A Musical Adventure. It's especially noticable in her Villain Song, "Evil Queen".
 * World of Warcraft features Gainax physics in the ears of the elven races, though more prominently in the Night Elves than the Blood Elves. The Night Elf ears stick out to the side and are very large so the bounce is easy to see. The Blood Elf ears stand straight up and are smaller but bounce just as much.
 * Their boobs move around quite a lot too. But actually, the boobs that bounce around a lot in World of Warcraft are on female undead. Sort of justified as they probably aren't attached properly anymore.
 * Take a look at the female dwarf's running animation; it's almost hypnotic. But other then the Night Elves and Dwarfs, the jiggling is surprisingly realistic for a game.
 * They even have a /silly that implies that they were originally attached to someone else. ("Yes, they're real. They're not mine, but they're real.")
 * The Pokémon Nidoqueen actually displays this in the Stadium games upon release and before executing a physical attack.
 * Blue-Eyes of Pokémon Ranger: Guardian Signs, despite being a tiny sprite, has visible Gainaxing when she does her Action Pose.
 * The World in her win animation in the puzzle game Magical Drop.
 * Magical Drop II.
 * In Magical Drop III (and to a lesser extent in the previous titles) nearly all of the female characters get this to some extent, but it's in nearly every animation for The World.
 * This happens during the opening cutscene of Namco X Capcom. Really establishes the character being from Soul Calibur.
 * Speaking of Capcom vs. Whatever, we had Rogue and Psylocke doing his when the Marvel crossovers really took off.
 * Early Golden Sun DS gameplay footage shows at least one summon with gainaxing.
 * BlazBlue has Litchi Faye-Ling. The resident Ms. Fanservice, Litchi has an extremely large pair of knockers that bounce even when she's seemingly standing still. There's a reason she's called "Boobie Lady", you know.
 * Also, fellow Ms. Fanservice Makoto Nanaya has this going on, although to a lesser extent. As an added bonus, if her theme music is playing in the background, her boobs bounce to the rhythm!
 * Tales of Vesperia: Estelle wishes she could bounce like Judith. Especially in the PS3-version.
 * Kongiku from Muramasa: The Demon Blade has very large breasts that tend to wobble and jiggle constantly, even when she's not doing much other than standing there, breathing. The jiggle isn't as exaggerated as the most extreme examples of this trope, but is quite noticeable.
 * The priestess Rao in Okami jiggles wildly every time you meet her, . Issun rarely refers to her as anything but "busty babe", even to her face.
 * It's mentioned in the game's official art book that one of the programmers created a "bounce and sway program" with "great attention to detail" to get Rao's breasts to jiggle just right.
 * Rao isn't the only one. There's the Stripperiffic wood sprite Sakuya, as well as the Draconian Dancers.
 * Zola in Blue Dragon. She's by far the better endowed of the two girls in your party(and it shows). So naturally, instead of a bra, she wears a blue tube top. Tube tops are not known for their supportive properties.
 * Female Selkies from Final Fantasy Crystal Chronicles.
 * The female protagonist from Epic Battle Fantasy's breasts can be clicked on and they jiggle
 * Every single game from Japanese H-game maker Illusion. Being strictly h-games they generally have controls that affect the size, shape, firmness, effects of gravity....
 * Surprisingly, somehow they seem to have averted (mostly) in their latest game which uses a different, much more realistic (for varying degrees of realistic) engine versus their traditional anime-esque style games. There is still bounce, but much less Gainaxey.
 * In one cutscene in Batman: Arkham Asylum, Batman tackles the newly Stripperiffic Harley Quinn by jumping on her through a pane of glass, causing her breasts to jiggle slightly.
 * Evident on Primal's Transformation Sequences. Especially when Jenn turns into a Wraith, which causes her breasts bounce faster than normally.
 * Dr. Naomi in No More Heroes 2: Desperate Struggle has a preposterous bounce animation triggered when the player speaks to her in the laboratory. The self-awareness of this is heightened by Naomi's comment, 'Quit staring at me! I know what you're thinking—and NO!' a nod to the fact that she appears to have grown since the first game in the series and been put in an impossibly small top. It is a simply wonderful piece of Fan Service.
 * It's also found in the intro to Pure White Lover Bizarre Jelly, a parody of Magical Girls and Moe.
 * Ms. Fanservice Kasuga from Sengoku Basara previously never displayed this despite sporting some impressive Absolute Cleavage. However the latest game corrected this with subtle yet realistic bouncing, as did the anime series (where her breasts are much larger than normal and it was not all subtle).
 * Being based on the WWE, it's a given with the licensed games. It does get hilarious in one of the older PlayStation 2 games, when you encounter them in cutscenes and their breasts jiggle noticeably every time they revert to their default position between dialog lines.
 * In Tokimeki Memorial Taisen Puzzle Dama, Yuko Asahina has some animated sprites where her breasts bounce.
 * And Tokimeki Memorial 4 has Fumiko Yanagi's breasts bounce in her Limit Break 's portait animation during battles, as well as when she appears in the game's mini-OVA.
 * All the female classes with even a sightly fanservicey outfit in Ragnarok Online have this. Is quite fascinating and disturbing to see the cutesy sprites' boobs bouncing when in idle battle mode.
 * There's an animated ad on this wiki for a game apparently called Pristontale2, consisting of your standard blue-skinned Hot Amazon in a backwards corset breathing in, breathing out, breathing in, breathing out...
 * Echidna from The Bouncer.
 * Tifa in Dissidia Final Fantasy Dissidia: Duodecim]] has this for her intro. She also calls out Zidane for staring at them.
 * It's also in a few of FF7's FMVs. Too bad it took until 10 for such physics to be in effect even in battle...
 * Gods Eater Burst has a small amount, but disturbingly, not for the human characters. Some female shape Aragami such as the Zygote, Sariel and Arda Nova Gainax quite a lot, most notably in Arda Nova's death closeup. Hell, one monster has a rack that may very well be visible from space!
 * Selvaria of Valkyria Chronicles. Most of her major scenes focus either on her flaming blue badassity, or her.. um, "talents", and the jiggling is truly astounding when the camera's on them. One particularly dramatic scene suffers because of the focus on her breasts bouncing around in different directions.
 * Akatsuki Blitzkampf gives us Marilyn Sue, who's popular with fans both for her powerful, hard-hitting fighting style and for her huge, huge jugs that bounce and swing every which way as she smacks around her opponents.
 * Princess Gwynevere from Dark Souls has some subtle Gainaxing with her tremendous Gag Boobs.
 * The female Boss from Saints Row: The Third Can fit into this trope if you slide her sex appeal all the way to 100.

Web Comics

 * Nauseatingly parodied in this Ctrl+Alt+Del strip.
 * One Gaia Online comic update shows Lex, Sasha, and Ruby jogging in anticipation of an Olympics-themed event. About half the fan-edits of said comic focus more on Ruby's bouncing jubblies than anywhere else.
 * Referenced in this Skin Horse strip where a hacked game of Mario Kart is described (but not shown, tragically) as having Peach not wearing a shirt and having a "Gainax bounce".
 * Discussed as a superpower in this Baked Goods comic.

Web Original

 * Kerry Callen uses this trope to parody Wonder Woman.

Western Animation

 * Jessica Rabbit from Who Framed Roger Rabbit?. Her breasts were purposely drawn to bounce in the opposite rhythm of a normal female's chest while walking; she bounces down when a real person would bounce up, and vice versa.
 * And they go "boing"!
 * Betty Boop was also known to do this in certain cartoons.
 * Hell, it's not even breasts, but Invader Zim got away with this through Zim's zit, aptly named "Pustulio".
 * Technically it was necessary though, as the whole jiggling thing gave the hypnotic effect it had.
 * Tiny Toon Adventures seemed to have a little fun animating a female anthro bear character called Julie Bruin (based on, and voiced by, comedienne and singer Julie Brown) this way in one episode. Here's proof.
 * That episode was animated by Tokyo Movie Shinsha. Coincidence?
 * In the third Bosko the Talk Ink Kid cartoon "Congo Jazz", a palmtree does this, with coconuts substituting for breasts.
 * Believe it or not, Teen Titans got away with doing this to Starfire from time to time.
 * If they had used the Stripperific Starfire from the comic books, it would be justified. But her costume in the cartoon was relatively modest and form-fitting. Raven, on the other hand, was more considerably blessed and only wore a leotard, yet we were never given that Fan Service.
 * Actually, a one piece leotard is much better at support than a two piece outfit like starfires, WB version or no. At her size she certainly would have bounced with athletic enough motion.
 * Justice League did this on rare occasion. In the episode "Grudge Match", Roulette did this in the second scene. Figures, as she was promoting a Cat Fight ring
 * In "The Cat and the Canary" the animators should've been given a bonus for the part where Black Canary takes off her jacket before she spars with Green Arrow.
 * And The Backyardigans does it with Tyrone's ears, particularly in season 1's opening (who cares if it's in Spanish? Just pay attention on the bouncing).
 * The "Caveman's Best Friend" episode has Tyrone control the bouncing of his ears, even though it looked more like flapping during that episode.
 * Several episodes of King of the Hill seem to have a rather excessive amount of closeups of Luanne's breasts while they jiggle.
 * Victor's mum from Corpse Bride is subject to this trope, although it's hardly your typical case seeing as how she's middle-aged and overweight.
 * Tripping the Rift's resident Ms. Fanservice Six was animated this way.
 * Ralph Bakshi's Fire and Ice features a very early (1983) pair of life-drawn (but hugely amplified) Gainaxing breasts on Princess Teegra.
 * Shadowcat from Wolverine and the X-Men had her breasts bounce when she went after the Creepy Child in the "Battle Lines" episode.
 * In The Little Mermaid Ursula, of all characters, got an inordinate amount of time spent on her to make sure she jiggled realistically.
 * Endive from Chowder was animated like this for a few moments in at least one episode. You could argue about the amount of fanservice, though.
 * Truffles got the treatment once, as well as Reubens.
 * Mrs. Beady from Barnyard and Back at the Barnyard has her boobs jiggle, even when she gets up from the chair.
 * Princess Vespa in G4's animated Spaceballs adaption is usually animated this way.
 * The animated short film, Loco Melones, shows two of the women's boobs bouncing. Don't believe me, search for the short.
 * The buxom old lady from Coraline bounces quite a bit, particularly when she shoves her sister out of the way using her breasts. The Fan Disservice levels are cranked up to eleven later on when she appears to be jumping on a diving board... naked.
 * Leshawna from Total Drama Island quite often, but it's very subtle.
 * This has happened on occasion to Lindsay as well.
 * Male example with Alejandro. No, seriously.
 * Manuela from the Les Lascars film is the embodiment of this trope. Even when she does the smallest movement like turning her head, her boobs move.
 * You're welcome.
 * Mixed with the video game type in the Megas XLR episode "Viva Las Megas. Goat is at a gaming convention. While discussing a new beach volleyball game with a guy, he says "I hope they improve the secondary motion engine."
 * Titania, a bartender from The Simpsons used this (combined with her natural talents) to her advantage in order to try and win the "Beer-Tender of the Year" contest. She loses when she refuses to throw out a drunk, telling Duffman that she slept with him to get out of participating in that part of the contest (Duffman's response: "Duffman says a lot of things! Oh, yeah!")
 * Like every female character, and some of the heftier guys, in this Confused.com commercial.
 * In the Regular Show episode "Muscle Woman", both Starla AND Muscle Man get this a lot, effectively squickifying the episode.
 * Aphrodite gives a little, light, slight boob shake when she turns in one episode of the animated Hercules series.
 * And the episode was...?
 * It was more than likely the one called "Hercules and the Dream Date", which was animated by Disney Toon, who often had the most detailed animation for Disney's animated shows back in the day.
 * Family Guy's interpretation of SabadoGigante.
 * Zatanna does it in the Batman Cold Open to the Batman the Brave And The Bold episode "Chill of the Night!".

Real Life

 * This actually is possible in real life, but more subtle than in Studio Gainax shows. And they probably won't move in different directions.
 * Not to mention that, depending on the size and level of intensity, it can be pretty damn painful for the person involved, and cause sagging in the long run.
 * Scientists are looking for ways to transform the sheer kinetic energy provided by bouncing breasts into stored electric power. At the very least, an ample chest could provide a source of current for your iPod.
 * This is no more or less practical than a kinetic generator clipped to the belt; scientists focusing on breast physics are simply making their own Fanservice. This is one way to draw attention to the technology, though; people remember and discuss the potential of boob power much more than the hip pack with the same functionality, which fell off the radar within a few days of reporting it.
 * Other scientists (and programmers) have created the simulator a level or two below the link to illustrate
 * How well their firm's sports-bra works
 * How well they know the physics of moving breasts, and how to simulate them in code
 * How many hits they can get from men with no intention of ever buying a sports-bra, ever.
 * Note: not work-safe in its default mode. Work-safe, maybe, if you eliminate the "nude"/photo example. Even less work-safe in wire-frame mode, for some of us at least.
 * This was shown in The League as a Porn Loophole
