Sakana/YMMV

"Taisei: Did I try to ride you like a bike last night?"
 * Angel/Devil Shipping: While not as popular as other pairings (especially the ship), people see the  ship as this, considering the former's status as a Pure Cinnamon Roll and the latter being a few steps away from Complete Monster status.
 * Cargo Ship: Jiro and Cheepii, the Cheapies donut mascot.
 * Complete Monster: Heavily implied with, there's a very good chance he'll turn out to be this trope.
 * Mad pushed this even further by calling him "the worst character in the entire webcomic" which, by the way, features freaking Yakuza. Brrr...
 * Die for Our Ship: Largerly averted.
 * Draco in Leather Pants: Japanese fans tend to view this way, due to his looks and attitude. The rest of the world has a very different opinion...
 * Ensemble Darkhorse: IT'S MISTER EEL HEAD!
 * For that matter also the crab that Jiro talked to in the first comic strip.
 * As of characters, Genkei has proven to be immensely popular despite his limited screentime. The fact Mad has confirmed him to be a crucial character (most likely regarding ) only added more fuel to the fire.
 * Later updates set Michio and Kento Kusagawa as this, both for their playful nature as well as worshipping Jiro.
 * Fan-Preferred Couple: TaiseixYuudai (affectionately titled TaiDai in most cases), so much that the artist even talked about their popularity in a Lifestream. A lot of the fanart of Sakana out there is featuring those two. Because of said popularity,, with JiroxYuudai taking up the mantle. Shigeru/Jan is very popular too, supported by the fact they're always seen together.
 * Really, many Slash pairings are popular enough, but one that sticks out is the ship. Talk about a Crack Ship!
 * Foe Yay: Taro and just scream Belligerent Sexual Tension at every turn. Mad even lampshades this.
 * Yuudai and would be just plain No Yay if the fandom wouldn't misinterpret their relationship as this.
 * Apparently, this is the appeal of the ship, due to the confirmed fact
 * Funny Aneurysm Moment: An object example. The "This Guy" hat was seen as nothing but an hilariously cheesy brand. Once enters the scene, most fans aren't going to look at the hat brand the same way again.
 * Yuudai hating being touched? Hilarious. Yuudai hating being touched ? Not funny at all.
 * Harsher in Hindsight: A lot of Yuudai's traits and behavior become less funny and more heartbreaking once his Dark and Troubled Past gets revealed.
 * Heartwarming in Hindsight: A mix of this and Harsher in Hindsight. Taro's protectiveness is heartwarming enough (not to mention hilarious), but it becomes doubly enough when you take into account, making clear Taro wants to keep his loved ones' safe
 * Hilarious in Hindsight: This movie. No, really.
 * Let's see: An Opposites Attract couple composed of a blonde Tsundere and a happy-go-lucky brunette whose trademark colors are green and orange and which is supported by most of the characters and fanbase? Sure this hasn't been seen before.
 * Angry Lady/ stating that "flowers don't betray you" becomes hilarious once Flowey is taken into account.
 * Ho Yay: Oh boy. Due to Taisei having No Sense of Personal Space, he oozes this. One example is his bromantic relationship with Jiro:


 * And there's of course also Taisei's meeting with Yuudai, where Taisei isn't discouraged at all when Yuudai behaves like a total Jerkass when he tries to find out Yuudais first name just after meeting him and enthusiastically tries every first name he knows, making Yuudai blush. And after Taisei pulls him into a brohug of sorts, he [Yuudai] freaks out like he was being touched in a inappropriate place. And you might want to interprete it like Taisei just being his usual self, but it all seems like Taisei is flirting with Yuudai. It's so blantant that Yuudai even asks Taro if Taisei is gay. Well, he is gay. He is one big ball of happiness that even Yuudai can't resist. It also doesn't help that Yuudai behaves like a massive Tsundere at times. Shippers of course have gone and run with this scenario.
 * This trope seems to be in effect whenever Yuudai and Taisei are alone: Taro leaves to spy on Jiro in disguise and Taisei and Yuudai find themselves alone, waiting for him. Then Taisei is exceptionally nice to Yuudai, making him compliments. Yuudai doesn't believe him at first, and when he finds out he is actually genuine with his kindness, he blushes heavily.
 * I Knew It!: Many fans correctly guessed the true identity of "Cashier Girl":
 * It was unanimously agreed by the fanbase that Yuudai was gay even before Mad revealed it in a strip. Also, many people cheered when
 * Incest Yay Shipping: Yes, there are Jiro/Taro shippers. The fact they're canonically very close helps. Same with Taisei/Genkei.
 * It Was His Sled: Many things concerning the true identities of some characters, namely "Cashier Girl", "Angry Lady" and especially "This Guy" . Then there's the I Knew It! entry above.
 * Jerkass Woobie: Yuudai. He's incredibly rude and abrasive to almost everyone he encounters, but this is confirmed to be a defense mechanism due to trust issues His status as this gets increasingly clear in later chapters.
 * The Angry Lady turns out to be this as well. She's quite angry and bitchy, but she used to be a lot sweeter until  Her statement that "flowers don't betray you" just drives this further.
 * Genji is a jackass who is frequently fighting with his family, but he has an awful case of No Social Skills and certainly doesn't deserve being screwed over by Nishimura and his gang.
 * Love to Hate: Ryoji Nishimura and his Co-Dragons, Endo and Billy, have picked up a fanbase.
 * An even greater example would be, whose status as a grades-weapon Knight of Cerebus Hate Sink has made him memorable in many fan circles.
 * Memetic Mutation: Whenever Taisei's eye shows up, things are going to be Serious Business/magical things are going to happen.
 * Taro throwing people down stairs whenever he get's serious/angry/protective of Jiro.
 * The reaction of Sakana fans to this movie were, to say the least, hysterical.
 * Jiro's hot new nose.
 * Pugging has become an in-joke between Mad and the fandom. Mad often answers questions about Sakana characters on her Tumblr blog. Whenever a question pops up which can't be answered since it would inevitably spoiler upcoming events in the comic, Mad instead posts a picture of a pug and claims to be too distracted by it's cuteness to answer the question.
 * And let's not forget Taisei's "ravish" line and face.
 * Mexicans Love Speedy Gonzales: Japanese and Korean people adore Sakana, to the point of having a fan translation circulating through the net, as well as having lots of fanart on Pixiv and Twitter.
 * Moe: Jan. Oh Jan. Just look at him enthusiastically presenting the menu, awkwardly waving with one hand in the background and trying to say Taro's name!
 * Moral Event Horizon: crossed the line both In-Universe and out when,  The fact he acts completely unapologetic about just clinches his status as a completely repulsive character.
 * Narm Charm: Normally, a character with a "This Guy" hat who uses telephone slang and the phrase "Hey, bud" would be very hard to be taken seriously... but manages to twist them around and make them genuinely terrifying.
 * Nightmare Fuel: The face Taisei makes in the last panel of this strip is kinda creepy.
 * A much more serious example are the interactions between Yuudai and . Let's be honest here, is pretty much Fridge Horror personified.
 * No Yay: Every ship involving . Especially the ship. Similar to Frollo, many people start shipping him with everyone in the cast.
 * Ship Mates: Take a seat...
 * There's the semi-canonical Jiro/Cashier Girl and Taro/Angry Lady (combined with )
 * Shigeru/Jan serve as this to Taisei/Yuudai. In fact, Shigeru/Jan is a popular Beta Couple with many pairings, since the vast majority take for granted the two are/will become a couple.
 * Then there's the Crack Ship, if only to include the latter into the main group.
 * Jiro/Taisei gets along rather well with either Shigeru/Yuudai and Taro/Shigeru. Jiro/Jan is also a popular one.
 * Some Anvils Need to Be Dropped: The current story arc has very important ones,
 * First:
 * Second:
 * Third:
 * The Woobie: It's really hard not to see Jiro as this. This makes it all the sweeter when things start going right for him.
 * Let's not get Taro off the hook either. He was a very troubled teen due to his vicious cousin rivalry with Genji, and feels really guilty for distancing himself from his brother in those years, trying to make up for it in the present.
 * Then there's poor Jan. Stranded in a foreign country he wasn't supposed to go in the first place, has a hard time communicating and fitting in, and according to Mad, he feels terribly homesick. He does have the Sakana cast as his friends, but damn...
