Your Mom

In a war of Volleying Insults, insulting the opponent's mother is a useful snappy comeback. These insults come in a variety of forms:

""Knock knock." "Who's there?" "Joe." "Joe who?" "JOE MAMA!""
 * The versatile "Yo' momma's an X!" (In the UK, substitute "yo' momma" with "yer mum", "yer maw" in Scotland, and "your ma" in Ireland. 'Ya mum!' in Australia).
 * The closely related "So's your mom!"
 * The similarly versatile "So's your face!"
 * "So's your mom's face!"
 * "So's your mum's face's university!"
 * "That's What She Said!"
 * And the similarly-related "That's what your mom said!", turning the insult into a Double Entendre.
 * Old knock-knock joke:


 * Often used when playing The Dozens. The classic example begins "Yo' momma so fat, [insert fat joke here]."
 * "Your mother wears army boots!" The implication is that she must have got them by bartering sex with a soldier for clothes. This particular one, referring to women in poor villages who would put out in such a fashion, has become a Dead Horse Trope.
 * A Spear Counterpart is the classic "So's your old man!", which was popular in the early twentieth century but has fallen out of use nowadays.
 * For characters in the correct age demographic, substitute "Your wife."
 * If one feels the need to elaborate, there's this version from the '80s: "Your mom. Your dad. Your bald-headed grandma."
 * Or "Your MAMA! Your big fanny granny! Your slap-happy grandpappy!"

As always, The Other Wiki gives much detail in the traditional deadpan presentation.

A "Your Mom" joke was found baked into a cuneiform tablet from 1,500 BC. However the punchline is missing, and it is possible that it could be a case of I Banged Your Mom instead. Which means one of those 2 tropes is Older Than Dirt and we don't know which.

Compare I Will Show You X, Lame Comeback, No, You, That's What She Said, I Banged Your Mom.

Be warned that seriously directing insults at someone's mother is generally not a good move, because Even Bad Men Love Their Mamas. Or if the character really does turn out to be the Son of a Whore then it might provoke more of a reaction than you were hoping for.

"Your Mom" insults work due to the Madonna-Whore Complex, which refers to how some people can only see a woman as a pure, sexless being or a depraved whore. Men tend to view their mothers as a part of the former category and implying that their mothers would have sex with someone who isn't their father puts her in the latter category.

 * The Nerd Core bumper on G 4 starring YTCracker, in which he states, "Mess with me you'll feel the wrath of Anon and Khan / We'll get that Rule 34 on Your Mom"

Anime & Manga

 * Goku, when attempting to get Uub (who was suffering from a massive dose of ring fright before his match with Goku) to fight by making him mad by insulting his family, says "Hey, yo mamma's so fat, cows moo at her!"
 * Canaan does this with Mino and Santana's mud-slinging match in the 5th episode, which eventually devolves into this sort of thing.

Comic Books
""Yo, why are they fighting?" "They're claiming first dibs." "On what?" "Your mom, of course." "... He's lucky I just took three Percocets.""
 * In the Clerks comic:

"Mek-Quake: (chasing Ro-Jaws) I will do unspeakable things to you! Ro-Jaws: (running away) Last night I did unspeakable things to your mother!"
 * A recent Spider Man comic sees a Let's You and Him Fight between Spider-Man and Deadpool degenerate into a gladiatorial battle of "Yo Momma" jokes (as in, they end up just standing in the middle of a basketball court firing zingers off at each other). After being pushed just too far by Spidey, Deadpool prepares to break out "Yo Mommageddon", a 'Yo Momma' crack he's honed so perfectly that it causes people to cry themselves to death (although in Hebrew it only makes people bite their own tongues off, as Deadpool learnt when he sold it to Mossad). He's just about to break it out when his beeper goes off, revealing that he's done for the day. He then cheerfully offers to buy Spidey a beer.
 * One of the kids who were watching the "fight" calls Deadpool out on it, claiming Deadpool was bluffing about the "Yo Mommageddon". Deadpool whispers HALF of the joke in the kid's ear, and he immediately starts crying.
 * In Ultimate Spider-Man, Spidey is fighting crime in a half-completed, bargain-basement version of his normal costume (the original was destroyed, and he didn't have a handy replacement.) He breaks up a mugging, and one of the crooks asked where his real uniform was. Spidey retorts, "Your mom's washing it for me." While beating them up, he admits that jokes like that are usually beneath him, but he's not exactly on his A-game.
 * Dogbert's Clues for the Clueless, Dogbert explains that, while insulting somebody's mother is impolite, "fathers are fair game." He illustrates this by rattling off a bunch of "your father is so dumb" jokes.
 * In ABC Warriors, during the Volgan War, Ro-Jaws provoked Mek-Quake into attacking him (thus saving the other Warriors) with a string of "Your mother" jokes. Blackblood tries to persuade Mek-Quake that, since they're all robots, none of them have mothers. It doesn't work. The greatest moment has to be this exchange:

"Scott: C'mon, man, dish! Got any embarrassing stories? Matt: Y-your mom is an embarrassing story!"
 * In Scott Pilgrim, during Scott's fight with Matt Patel, Ramona's First Evil Ex-Boyfriend, Scott tries to rattle Matt by asking about the time Matt and Ramona dated.

"Scott goes to rescue her. Final Boss is Simon Lee. Simon Lee: So, this is the best St. Joel can muster? Scott: That's not what your mother said last night!"
 * High School Flashback - The evil Benvi Tech boys kidnaps Kim P.

"Detective Lowe: You're probably in a hurry to get home to your little lady or whatever you call her, huh? The night time is the right time for love and all that, right? Detective Montoya: That's what your mother tells me."
 * The Half a Life arc of Gotham Central revolved around the involuntary outing of Renee Montoya, who has already had to deal with being a Hispanic woman in the predominantly white male Gotham City Police Department. When it is revealed that she is also gay a lot of the other GCPD detectives, who dislike her and the Major Crimes Unit as a whole because of their basic honesty in the highly corrupt police force, begin insulting her even more. Renee, however, has never been one to just take the abuse when other people decide to dish it out.

Literature

""Something about...your...wait...deine Mutti, as you would say, your...your mamma, she plays third base for the Chicago White Stockings, nicht wahr? A quite unappealing woman, indeed she is so fat, that to get from her tits to her ass, one has to take the 'El'! Tried once to get into the Exposition, they say, no, no, lady, this is the World's Fair, not the World's Ugly!" "Um, Your Royal Highness? If we could just have a word--" "It is all right! I know how to talk to these people! I have studied their culture!""
 * Note that earlier, when one boy says something critical about his friend's father, this is considered a serious breach of etiquette, whereas taunts about mothers are understood to be kidding.
 * Happens in Thomas Pynchon's Against The Day when Archduke Franz Ferdinand of Austria visits a black neighborhood in Chicago in the 1890s.


 * Invoked by Butler in the first Artemis Fowl book, where he uses a mother insult to lure some dockworkers out.
 * In the Star Trek Expanded Universe novel I, Q, the war between the Q Continuum and the M Continuum started when one of the M, after a discussion of why there needed to be a war which nobody could get worked up about, suddenly said "Your mother!"
 * Made even more hilarious by the fact that, since both the Q and the M are omnipotent, immortal beings, none of them actually had mothers!
 * In Jessica Layne's Knight Moves, a Middle Ages knight is challenged by stereotypical black Philadelphia gangsters to a "Yo Mama" contest.
 * Harry Potter uses it against Malfoy in Harry Potter and The Goblet of Fire, after Malfoy insults Ron's mother. "You know your mother, Malfoy? That expression she's got, like she's got dung under her nose? Has she always looked like that, or was it just because you were with her?"
 * He also pulls one on Seamus after Seamus calls Harry a lying liar who tells lying lies that lie.
 * Marge throws one in Harry's direction early on in Prisoner of Azkaban. It doesn't end well, and Harry himself is struck with guilt until Cornelius Fudge tells him that was OK due to the circumstances going on at the time (specifically, an escaped murderer/magic user on the loose in Mother England).
 * A Portrait of Yo Mama as a Young Man takes this trope and Crosses the Line Twice with it.
 * In Nanny Ogg's Cookbook, we're told that in some troll dialects, which rely a lot on guesture, extending one's hand to a troll is "a very bad remark about his mother". Apparently, it was some time before humans and trolls worked this miscommunication out.
 * Kevin teases the schoolyard bully Bertram with one of these in The Eyes of Kid Midas. Bertram is not amused--Even Bad Men Love Their Mamas.
 * In The Wise Man's Fear, an ordinary mercenary attempts to pick a fight with Adem mercenary Tempi by suggesting that Tempi's mother was a whore. This falls rather flat as A: Tempi is unfamiliar with the Aturan word for "whore" and B: Ademic culture does not have a stigma against prostitution.
 * Once he's been made to understand what the other man said, he thanks him for speaking so kindly about his mother.
 * This is the insult that sparks the whole plotline in Scaramouche.
 * Your mother is a tortoise is made into a running gag in Much Fall of Blood.

Live Action TV
""You're lookin' a little slow tonight, Dennis." "That's cuz your momma kept me up all night!""
 * A Celebrity Deathmatch between Michael Jordan and Dennis Rodman starts like this:

"Foreman:How many of those have you had today? House: I don't know. Is "your mother" a number?"
 * Star Trek: Enterprise pulled this in the Mirror Universe episode. During an interrogation of a Tholian, Hoshi interprets one of his defiant remarks as "something about your maternal ancestor".
 * One of the most offensive Klingon insults is "Hab SoSlI Quch!", which translates to "Your mother has a smooth forehead!"
 * House has a (deliberately) cringe inducing moment when Chase attempted a Yo mamma joke. It was horrific.
 * Youtubage! (Probably not brain safe. Horrific is right.)
 * Used subtly (well, as subtle as a your mom joke can be used) in later episode.

"Angel: "Another minute, and I would have given them everything. The ring, the scroll, your mom... how is your mom, anyways?"
 * MTV had an entire show based around this trope, appropriately titled Yo Momma and hosted by Wilmer Valderrama (yes, THAT Wilmer Valderrama).
 * In years before that, they would include ad bumpers of New Yorkers trash-talking each other in various settings (usually at one of NYC's famous public basketball courts).
 * Angel

"Puck: Hey ankle grabber! I had sex with your mother. No, seriously. I cleaned your pool, and then I had sex with her on your bed. Nice Star Wars sheets."
 * From Glee:

"Kearin: All you FOBS have man boobs! Jonah: Yeah, well ya mum has man boobs! "
 * Summer Heights High

"Roy: Nice glasses! Moss: Not as nice as your mum's glasses! Roy: Still a little bit complimentary, but it's getting better."
 * In an episode of The IT Crowd, Moss has been bullied and Roy attempts to help him stand up for himself by roleplaying:

"Christian: Ah. Samuel's locked office. Pretty private. Who you calling? Dean: Your wife. Let her know I'm not gonna make it over tonight."
 * In Supernatural's 6.07 "Family Matters", Christian Campbell catches Dean snooping around Samuel's office. As Dean comes up with a weak excuse about needing to call someone in privacy:

 * A constant theme in The Mary Whitehouse Experience's History Today sketches.
 * The E4 Voiceover Man got a great one during an advert for School Of Comedy.

"Liz Lemon: Okay I'll do it, but I won't like it. Jack Donaghy: That's what your mom said last night. Booyah."
 * Thirty Rock: "What's the difference between your mum and a washing machine? When I dump my load in a washing machine, it doesn't follow me around for a week afterwards!"
 * Followed by Jack's rather surprising one when he asks Lemon to go to a fancy royal birthday celebration with him.

"Trebek: This is the sound a doggy makes. Sean Connery: Moo. Trebek: That is incorrect. Sean Connery: Well that's the sound your mother made last night! Trebek: ...We would have accepted "bow wow" or "ruff". Sean Connery: Ah, rough! Just the way your mother likes it, Trebek!"
 * Liz gets in on it too.
 * Sean Connery in the Celebrity Jeopardy! sketches on Saturday Night Live would repeatedly throw these at host Alex Trebek:

"Sean Connery: It's been a long time Trebek. Trebek: Not long enough. Sean Connery: That's not what your mother said last night!"
 * or:

"Contestant: Alex, I'll take "Your Momma!" for $400."
 * Also played with in the "Mother joke of the day" on the Talk Show parody I'm Chillin.
 * Jeopardy! itself had a category called "Your Momma!" on 12/16/2010, which brought laughter the first time a contestant picked it. The exact wording didn't help...

"Barney: Whoa, Ted, that thing you're packing is way too big to fit in that box. Ted: Yeah, that's what your mom said. Barney: How dare you! Ted: No, she actually said that. Barney's Mom: (walking in) Oh, dear, I thought I told you, that's just not going to fit in there."
 * From How I Met Your Mother, when the gang is helping Barney's mother move:

"Al: Any last words, punk? Gang member: Yeah, your wife's good in bed! Al: So, you're a liar, too! (punches him)"
 * In the Married With Children episode "Bearly Men", Al is about to fight with a street gang:

"Host: (deadpan) "Yo mama so hairy..." ("T-Dogg" buzzes in) Host: T-Dogg "T-Dogg": Yo mama so hairy, Big Foot be takin' pictures of her."
 * Bud and Kelly will often insult each other with barbs along the lines of "Eat Mom's cooking/Smell Dad's shoes". And have no problems saying it in front of their parents.
 * A recurring sketch on In Living Color had a Game Show called "The Dirty Dozens," in which the host would supply the first part of the insult, and the contestants would ring in to finish it. For example:

"Bashir: Quark, leave it! Quark: I can't leave it, it's all that I have. My personal mementos, my family album... Bashir: It's full of gold-pressed latinum, and you know it. Quark: ...Who told you? Bashir: Your mother did, the day you were born. Quark: NEVER-MAKE-FUN-OF-A-FERENGI'S-MOTHER. Rule of Acquisition Number 31!"
 * Subverted when some of the categories don't lend themselves well to the joke: i.e. "Yo' momma so good at math ..."
 * Later in the series they made "spinoff" versions such as Wheel of Dozens and Family Dozens.
 * The dirty dozens are Serious Business for Mo and Marcus of Smart Guy, who treat it like a martial art, even bowing before and after a match. Hilarity Ensues when they attempt to instruct Marcus' little brother TJ, the titular smart guy.
 * Star Trek: Deep Space Nine:
 * In "The Way of the Warrior", Klingons attempt to insult Odo in Klingon, and Garak replies with "Actually, I'm not sure Constable Odo has a mother."
 * This exchange in "The Siege"

"Kirk: "What can you expect from a simpering, devil-eared freak whose father was a computer and his mother an encyclopedia.""
 * In the EU, the full rule is "Never make fun of a Ferengi's mother - insult something he cares about instead." That said, Quark does care about his mother more than most Ferengi.
 * In one episode of Star Trek: The Original Series, Kirk has to try and snap Spock out of the influence of mind-altering spores by making him angry:

"Gene: Serves you right for staying up all night rutting with that new fella of yours. D'you let his guide dog watch? Phyllis: His guide dog's giving your mam one. From behind. (Sam smirks) Gene(to Sam): Whatever 'appened to all the classy birds?"
 * Doctor Who:
 * In "The Vampires of Venice", Amy's fiance Rory, attempting to draw the Monster of the Week away from Amy, tells it "The only thing I've seen uglier than you is your mum!". The monster's reaction cues an Oh Crap look.
 * Kind of subverted in "The Girl in the Fireplace". When the Doctor (who is probably drunk) confronts the clockwork robots, he says "You're Mr Thick Thickity Thick-Face from Thick Town, Thickainia... and so's your dad."
 * "The Runaway Bride": Donna and the Doctor are stuck in the middle of nowhere, and are trying to take a cab back to the church. Eventually they realize neither of them has any money. The cabbie dumps them out and all we hear is Donna scream, "And that goes double for your mother!"
 * Phyllis uses this to get one over on Gene in Life On Mars.

"O'Neill: ...And after that, I kind of lost my temper. Hammond: What exactly does that mean? Jackson: Let's just say Jack made a reference to Freyr's mother."
 * In the Stargate SG-1 fifth season episode "Red Sky", O'Neill and Jackson recount how a particular negotiation with the Asgard went south:

""You bowl like your mother, unless she's a competent bowler, in which case you bowl nothing like her""
 * In The Big Bang Theory, Sheldon gets in on the Yo Mama action twice.
 * When attempting to trash talk before a bowling match

""Also, I'm given to understand that your mother is overweight. Now of course if that is a result of a glandular condition and not sloth and gluttony, I withdraw that comment.""
 * And trash talking before a Robot Wars style battle

"Dorothy: Now are there any questions? Kid: Yes, Ms. Zbornak, what does Joe have to say about all this? Dorthy: Joe who? Kid: Joe Mama!"
 * On one episode of the 60s Batman TV series, a villain (I think it was Shame) taunted Batman with, "Your mother wears army boots!" To which Batman responded, "Why yes, she does... and she finds them quite comfortable!"
 * Fresh Prince of Bel Air: Phillip Banks had an excellent response to this, in a scene that is Papa Wolf, Crowning Moment of Awesome, and Crowning Moment of Funny in one shot.
 * Smart Guy had Marcus and Mo teaching TJ to do the Dozens as a method of countering a bully who is mocking his ear size after his attempt at ignoring the bully failed outright. Although it was initially successful, it ended up backfiring on him when one of TJ's "Yo Momma" jokes (well, technically "Yo daddy", but still), "Hey, yo dad's so ugly that he ended up arrested for mooning", turned out not only to be very much true, but was also the bully's Berserk Button, as apparently he has to become the man of his household to fill in the void of the father's jailtime, the stress relating to it and craving for attention as a result acting as the very reason why he often has to bully others.
 * Golden Girls had this a few times in an episode. Made funnier by how in a second scene it was Sophia, Dorothy's mom, about to say the line.

"Doña Florinda: Next time go act like a clown with your grandmother! Chavo: Don Ramón, your granny likes the circus? Don Ramón: TOMA! (hits Chavo) And I won't hit you twice only because my granny was a trapeeze artist..."
 * One episode of Castle: Ryan and Esposito, two extremely close friends, are captured by the Big Bad. Ryan is tortured while Esposito is Forced to Watch. Esposito says he can't stand it anymore, and tells the Big Bad: "Listen to me. You're too late. The cops already know everything about... me and your mom." Then he starts cracking up.
 * In El Chavo del Ocho, whenever Dona Florinda slaps Don Ramón for something she thinks he did or tried to do, she usually tells him to do it to his grandmother. If El Chavo is around, he usually asks Don Ramón something about said grandmother. Feeling offended by the question, Don Ramón hits El Chavo and usually comments something about his grandmother as the sole reason he won't hit Chavo a second time. Example:

"Tim Taylor: Your mother is so large, she might end up being your mothership. (Al Boarland then proceeds to attempt to chase and presumably attempt to beat up Tim for that remark as Tim leaves the set, the only thing stopping Al being the harness that's keeping him on the "roof.") In another episode:"
 * Dona Florinda's attitude is somewhat justified by the fact she and Don Ramón's grandmother are acquaintances and don't get along.
 * In Home Improvement, Tim Taylor often utilized this trope on his "Tool Time" co-host, Al Boarland. In the episode where Tim dreamt about an alien encounter and then during a show about roofing (while speculating that Al may be an alien):

- Tim Taylor: Your mother is so large, she has her own zip code.

"Barbarino: Hey, say whatever you want about my dad or myself, but you don't talk about my mother! That woman's holy."
 * Averted in Welcome Back, Kotter, when Kotter contrasts the Dozens with the "modern" (1970s) style of insult-duelling starting with the beginning of a classic "Your momma..."

"Burns: This place is a mess. Hey, I made a joke! Houlihan: So did your parents."
 * Mash - Winchester is angry with Hawkeye and B.J. and stops talking. The two try to goad him out of his silence, saying to him "Your mother wears very expensive combat boots!" and very nearly getting him to crack with "Your parents voted for Roosevelt. Four times!"
 * This exchange in the mess tent between Burns and Houlihan, post-breakup:

"Alec (in British accent): Actually, I need it for a ride on your mum."
 * WKRP in Cincinnati - Herb reluctantly buys a painting at a charity sale to score points with the boss - Bailey likes it and says so, and he gives it to her. Later he hears it may be worth a fortune and tells her he wants it back, saying "I meant 'It's yours' like a figure of speech, like 'I love you' or 'So's your mother!'" When she won't give it back he tells her "I'm very disappointed in you." She looks conciliatory and says "Herb? [flatly:] So's your mother."
 * In an episode of Dark Angel, when Alec confronts a gang of steelheads who are monopolizing the steroid black market he's trying to break into, a British steelhead named Eddie asks what he needs five hundred dollars for.

"Stormtrooper: Who are you?
 * CSI: The owner of a brothel that is a crime scene gets annoyed when Nick won't speed up the search to let him reopen the rooms and comes out with the unusual gem "Your mother sleep with Azerbaijani!"
 * Played with in the Mystery Science Theater 3000 version of "Santa Claus Conquers the Martians", when Santa greets a Martian family, and the Bots start quipping, "And so's my dad. And so's your dad! And so's your mom! And your sister swims out to troop ships!"
 * Community: Used in a Crowning Moment of Awesome.
 * Your mother's lover. [shoots]"


 * During an episode of Hill Street Blues, when peace talks between two street gangs broke down, one of the gang leaders shouted at the other, "I kissed your mother five times!"

 * And from Styx's concert video Caught in the Act, taking place in a prison full of robot guards: 'Hey, Roboto! Yer mudda was a Toyota!'
 * "Yo Mama" by Butterfingers: "Yo mama's on the top of my things to do list!"
 * This Fatty Spins song.
 * The D&D song, only in the "Live at the El Rey" version, contained the following lyrics at the very end.

""We're not that big on Yo Momma jokes in Canada..." "Yeah, we go 'Eh Momma'...""
 * From Whose Line Is It Anyway, one session of Hollywood Director had Colin "ordering" his "actors" to redo the scene in Yo Momma jokes.

""So be kind to your mother Though she may seem an awful bother And the next time she tries to feed you collared greens Remember what she does when you're asleep!"
 * The Decemberists' "A Cautionary Song":


 * "Your Mama Don't Wear No Socks" was a popular summer camp song. I saw her when she took them off!

Well, she can touch rim still."
 * In the wake of 9/11, Ray Stevens released "Osama — Yo' Mama".

Newspaper Comics
"Scale: Let me put it this way... Have you ever considered a career as a river barge? Garfield: Your mother was a blender! Scale: That hurt."
 * Garfield has several G-rated versions:
 * When Garfield stands on the talking scale:


 * When he does his act on the fence, he tells his audience: "All you your mothers wear army boots!"
 * He said this to a dog once, who merely walked away thinking "He's lucky Mom was in the military."
 * Jon tries to train Garfield to be an "attack cat", and makes a dummy from him to practice. When he orders "Attack!", Garfield tells the dummy: "Your mother wears combat boots!"
 * When Garfield is a bad mood, he shouts to a bunch of dogs: "All your mothers wear flea collars!" which gets him beaten up.
 * Garfield barks something to a chained dog, who gets really mad. Garfield explains that it meant "Your mother has fleas".
 * In one of the rare occasions in U.S. Acres where Booker achieves some sort of victory against the worms, he looked into a hole, which Booker then plugged with a cork. Booker then yelled, calling the worm's mother a "garden hose". As Booker expected, the worm hit its head at the cork while trying to return to the surface to respond to the insult.
 * In a later U.S. Acres story, a worm told Booker his mother swam after garbage scows. Booker reacted by trying to go after the worm, who then retreated itself into a hole where Booker got stuck. Then Orson, whom Booker affectionally calls "Mom", showed up wearing a swimsuit and telling Booker to hurry up because the garbage scow was coming down the creek. Booker groaned in frustration.
 * Feeling bored, Wade told Cody his mother had fleas so Cody would chase him away.
 * One FoxTrot strip has Jason and Marcus trash-talking each other before a test with "your momma" lines. This strip led to the name of one of the compilation books, Your Momma Thinks Square Roots Are Vegetables.
 * Caesar from The Boondocks is a walking encyclopedia of this trope.
 * Curtis is always getting these from the strip's two bullies, Derek and "Onion".

Professional Wrestling
"Bobby Heenan: Last week he repoed his own car. Gene Okerlund: About five years ago, he got my mother-in-law. Bobby Heenan: About four years ago, everybody got your mother-in-law."
 * During Repo Man's entrance at the Wrestlemania X-7 Gimmick Battle Royal:

Radio
""Ah, your mother drinks warm beer!""
 * Alice does this in The Phil Harris-Alice Faye Show when she runs out of intelligent comebacks, some of which are dated if one doesn't know the pop culture reference. Others are more general like:

Theater
"Painter: You're a dog. Apemantus: Thy mother's of my generation: what's she, if I be a dog?"

"Launcelot: Marry, you may partly hope that your father got you not; that you are not the Jew's daughter. Jessica: That were a kind of bastard hope, indeed! so the sins of my mother should be visited upon me! Launcelot: Truly, then, I fear you are damned both by father and mother; thus when I shun Scylla, your father, I fall into Charybdis, your mother."
 * The Merchant of Venice:

Video Games
"Ellis: Hey Nick, what kinda car you drive? Nick: Your mom's car. Ellis: See, that was just uncalled for."
 * "At least my mother doesn't make a living on her back!"
 * Team Fortress 2's Meet the Spy as quoted above—the BLU Spy even backs it up with pictures of the RED Spy... fraternizing with the BLU Scout's mother.
 * The Spy also have a in-game domination line that might get triggered when dominating a enemy Scout: "Well, off to visit your mother!"
 * One of many dialogue snippets that plays upon reaching an abandoned impound in Left 4 Dead 2:

"Vierri: Are you afraid to handle things yourself? Ezio: Your sister seemed quite satisfied with the "handling" I gave her."
 * Upon seeing a Spitter, Ellis sometimes calls, "It's Nick's mom!"
 * Ezio uses a variation to make a snappy comeback in Assassin's Creed II.

"Mr. Monkey: Ahhh! Damn it! Y-You're just a big loser! I'm able to skip the rock as many times as I want! So there! Ha-Ha! Loser! Moron! Idiot! Your mum wears combat boots!"
 * Of course, given that this is Ezio we're talking about, odds are that's NOT just a snappy comeback.
 * He also plays this trope straight in at least one of his combat taunts: "Your mama can't help you now!"
 * Sam and Max use these in Episode 103 ("The Mole, The Mob and the Meatball") against a card sharp (who is very sensitive about his mother) to get him to cough up the location of a meatball sandwich.
 * "I would've been yo' daddy, but the dog beat me over the fence!"
 * Final Fantasy VIII, of all games.

"Sketch: Tight fit for Tug. Tug: Eh, that's what your mother said."
 * In Neverwinter Nights 2, a female character can respond to Bishop's opening suggestion that she go back to whatever brothel she came from with "Good idea. I'll say hello to your mother while I'm there, shall I?"
 * In the Leliana's Song DLC for Dragon Age: Origins, Tug and Sketch's sniping produces this gem when they're about to climb through a window:

"Grubba: Hyuk hyuk! Your challenger is real confident, boys! Yep, he's talkin' trash... "Iron Adonis Twins?" he said. "More like Paper Dog-Face Bros.! ...And they stink!" And then he said: "I bet they just play video games an' cry when they lose!" Um, yeah, and then he said... "Outie belly buttons run in their family! Stinkwads!" ...And so on. Yep. Iron Cleft #1: WHAAAAAAAAAAAAAAAAAAAAAAAAAT!? How does he know Mom has an outie? That jerk! We're gonna blend you up into a smoothie, pal! And then we're gonna drink ya! Oh, and one more thing... Only smelly stinkwads call other people stinkwads! Understand, stinkwad? Iron Cleft #2: Simmer down there, Bro. You! Stinkwad! You're gonna regret opening your yap, pal! See these bods? Solid iron. See these spikes? Yeah, they penetrate any substance. So, basically, what I'm telling you is that whatever you try will be completely useless. Think that over in the very short time you have left with a functional brain."
 * Paper Mario: The Thousand-Year Door did a variation, where Grubba told the Iron Adonis Twins' that Mario was talking trash about them (hint: he's not), and one of the trash talks also had them being offended due to the fact that their mom had an outie.

"Sten: Dwarf. Oghren: What? Sten: Stop tripping me. Oghren: Stop tripping yourself! Sten: If you were significant enough to notice, I wouldn't step on you. Oghren: Oh, well... your mother! Sten: ...That was disappointing. I expected better from you. Oghren: Sorry, I was in a rush."
 * SimAnt had a few, if you turned on dialogue. If memory serves, one of them was "your mother was a termite!"
 * In one of the party conversations in Dragon Age Origins:

"Varric: I swear, when I find that son-of-a-bitch - sorry mother - I will kill him!"
 * Dragon Age 2 had an inadvertant one . Varric had this to say about his brother.

"Alfredo: Your mother wears combat slippers! Bill: Leave our mother out of it! Get in the cannon!"
 * In RuneScape's "A Clockwork Syringe" quest, one of the insults you can use while interrogating a zombie pirate is "Yo momma has enough chins for 99 range!"
 * Typing "UR MOM" in Scribblenauts gives you a Zombie.
 * In The Secret of Monkey Island, "So's your mother" is one of the options in Insult Swordfighting that won't win, although it only appears during the training scene with Captain Smirk. Also, if you let the Fettucini Flying Brothers argue over who gets to go in the cannon:

"Rlaan pilot: Your female ancestor was promiscuous! Wait... how is that not a compliment?"
 * In The Curse of Monkey Island, one of René Rottingham's rhyming swordfight insults is "Your mother wears a toupee!", to which Guybrush can respond, "Oh, that is so cliché", which is the same response to a pirate's "En garde! Touché!"
 * In Tales of Monkey Island, Guybrush gives us, "Your mama's so fat, it's probably a serious health risk for her. She might want to visit a physician about that."
 * In Shining Wisdom: "Your mama's so ugly she looks out the window and gets arrested for moonin'!"
 * One of the conversation choices in The Sims 3 (and also The Sims Social and The Sims Medieval) involves calling a Sim's mom a llama.
 * In Fable III during the "Gnomes Are Evil!" quest, Lionel the gnome interjects "Your mother!"

 * Marvel vs. Capcom 3: Deadpool yells "YO' MAMA!" at random when he executes his standard strong attack.
 * In Sly 3, Bentley has to goad Muggshot into a fight as part of a plan. The one thing that'll make him reconsider fighting a wheelchair-bound turtle? Making a nasty comment about his mother.

Web Animation
"Palmer: "Do you like working for us, Mr. Matthews? Does the job satisfy you?" Raimi: (Inner Monologue) "About as much as your mom did last night.""
 * Even Broken Saints isn't afraid of this one:

"Phil: My mom just called. Joel: Your mom just called. Phil: ...excellent comeback. Joel: (oblivious) I know."
 * In The Guild, the Cliff Hanger for one season 3 episode is a member of the Axis of Anarchy.
 * Bonus Stage uses Your Mom jokes way too often.

"Joel: Your mom's a world. She's my world. I guess "Your Mom" insults pack less of a punch now."
 * In one episode, the two girl characters agree that Your Dad jokes will never catch on.
 * When Joel actually ends up going out with Phil's mom, Jessica, he discovers that Your Mom jokes don't make sense anymore.

 * And as a sequel to that, the zinger in the next video said: "Contrary to claims made in the previous video I have not in actuality fucked your mum because damn that shit is nasty, yo"
 * "By the way, it's okay to swear on the internet. Your mum isn't likely to read it. I know, because she's too busy being fucked. By me."

"Freeza: "Well, Vegeta, time to send you crying home to mommy." Vegeta: (in extreme pain) "My... mother's... dead." Freeza: "I know.""
 * Which is then chillingly referenced by Freeza during his fight with Vegeta:

"Bardock: "We need to raise an army, and-" Random Saiyan: "Your mom's an army!"
 * It also happens in Bardock The Father of Goku.

"Tucker: Freelancers are independent, they're not red or blue. They're just guns for hire, who'll fight for whoever has the most money. Caboose: Like a mercenary. Tucker: Right. Or like your mom, when the rent's due. Caboose: ...oh, that's funny. Tucker: Yeah, you didn't think that was too obvious? Caboose: No no, no no, that was, that was good."

"Nostalgia Critic: Any chance you have Sean's number? Cinema Snob: Your mom has Sean's number. Nostalgia Critic: Shut up."
 * Kickassia covered this trope early, when The Nostalgia Critic called The Cinema Snob:

"Chris: Mr. Critic, what are your plans now for this new glorious nation? Doug: ......I'm doing your mother."
 * Played for Laughs in one of the bloopers, when Doug forgot his line:

"Neil and Nathan: We did not get along Nathan: I thought Neil was given far too many songs Neil and Nathan: Both threw insults at each other Neil: Told you how I f#!ked your mother..."
 * In the Commentary! The Musical song, Ninja Ropes:

 * Two Best Friends Play has several:

"(After Pat is poisoned and killed) Pat: Aw, fuck! Matt: Ahaha! Yeah, you're a real combat specialist! Pat: Your mom is a fucking combat specialist. Matt: What? Pat: With my dick."

"Yo' mama, is like a brick: she's dirty, she's flat on both sides, AND she always gets laid by Mexicans!"
 * Left 4 Farts has the gang jokingly exchanging Your Mom insults on a building's roof while Francis is dangling over the edge of said roof. Zoe finally comes up with this gem:


 * Strong Bad apparently attempted one in response to an annoying request from a Polish viewer, but it comes out as "Your mother is the speed limit" ("Twoja matka jest ograniczenie prędkości"). Oddly enough, this isn't a case of My Hovercraft Is Full of Eels because both the email and his response are typed in English and translated by a voiceover.
 * There is a channel on YouTube, appropriately named Yomama, dedicated to animating just about every Yo Mama joke in existence. New videos are posted every Monday and Friday, and our host is a lovably obnoxious blonde Gaston Expy named Brody. It's all quite entertaining, actually...

Webcomics
"Boy: Well, your mom turns every conversation into a "your mom" joke and it's becoming unbearable. Girl: I'm serious; I can't take this anymore. I'm leaving. Boy: ...That's what she said! Girl: Yes. Yes, it is."
 * xkcd #366

"Wolf: Your mozer's a whore. Ocelot: Thanks! Yours too."

 * Also beautifully subverted in #502.
 * The XKCD writer/drawer is a genius for managing to turn a stupid Your Mom joke into a genuine Tear Jerker.
 * Another one in #639.

Try probing a bit deeper. Mantis: If I go any deeper I could cause serious damage. Ocelot: That's funny- I said the same thing to your mother last night. Mantis: [Death Glare Ocelot: In bed Mantis: [Throws plant pot at Ocelot]"

 * In The Order of the Stick Roy tries to get the Oracle's attention  with "yo mama" insults.

 * This was Aigis's response to Akihiko as to why she, a robot, couldn't open a door.

As the comic writer points out, this is actually possible in the games on which the comic is based.

Real Life
"Sen. Kyl: I don't need maternity care. So requiring that on my insurance policy is something that I don't need and will make the policy more expensive. Sen. Stabenow: I think your mom probably did."
 * A common Chinese insult is "肏你妈 / 操你媽" (cào nǐ mā, pronounced "tsao"), which literally means "fuck your mother".
 * In Russian, you can say "Ёб твою мать" (yob tvoyú mat'), which means exactly the same thing.
 * Similarly, the worst insults in Arabic (in Egypt at any rate) are kuss ummak and aḥḥa ( both figuratively "fuck!", "fuck that!", or "fuck you!" depending on context), literally translate to, respectively, "your mother's vulva" and...well...it's hard to explain. Let's just say that aḥḥa is derived from aḥḥ, which is the Arabic onomatopoeia for a woman having an orgasm...
 * An example from...the United States Senate? Yeah, sure, why not.

"Glenn McGrath: "Why are you so fat?" Eddo Brandes: "Because every time I fuck your wife she gives me a biscuit!""
 * Debatable in real life, because the comeback's been attributed to at least two different people: supposedly someone poked fun at a bald man by running a hand over his head and saying, "Your head feels just like my wife's butt!" Of course, that opened him up to the bald man stroking his own head and saying, "Why, so it does!"
 * This similar exchange, often considered one of the funniest incidents in sports:

""... of your mother, is by the one who has intercourse with her. Who is it?""
 * Ancient Germanic tribes, like the Anglo-Saxons and the Norse, opened all their battles by trading insults about their mothers.
 * In the late Roman Republic, Cicero was known for his wit. When a man named Metellus repeatedly asked him "Who's your father, Cicero?" he replied, "For you, your mother has made the question difficult to answer."
 * For a little context, Cicero was a novus homo (new man), meaning nobody in his family had ever been a senator or a member the Roman government before. Asking who his father was a way of insulting him and saying that Cicero was a nobody, which given how the Roman Republic was far more of a oligarchy than a modern republic, was a big insult and a big impediment to being taken seriously.
 * This Text From Last Night is a double example, combined nicely with Insult Backfire.
 * Profanity in Latin countries commonly centers around insulting other people's mothers. "Chinga tu madre," or "fuck your mother," is often considered one of the most potent insults possible in Mexican Spanish. "Tu madre es una puta" ("your mother is a whore") or "hijo de puta" ("son of a whore/bitch") has similar effects in many Latin American countries. In Puerto Rico it's sometimes shortened to "tu madre".
 * A common comeback is to say "tu jefa" (literally meaning 'your female boss', actually meaning 'your mom')
 * Note that this is used by women as well as men. It's especially funny when a woman calls her own son "un hijo de puta", which happens more often than you'd think.
 * The usual way to return an insult or to turn a statement into one is to use "tu abuela" or "su abuela" (your grandmother!).
 * Since the Philippines was a Spanish colony for a few centuries, the word "puta" has made it's way into the native tongue. "Putang ina mo!" (your mother is a whore!) is the most beloved of all curses used by everyday Filipinos, although the shorter "'tangina!" has since devolved into an expression of disbelief, among many other meanings.
 * In Brazil (and possibly other Latin American nations), one category of people known for having their mothers insulted like that are soccer referees.
 * Crossing over somewhat with I Banged Your Mom: In an Australian Rules Football match between the St Kilda Saints and the Brisbane Lions, Brett Voss (playing for St Kilda) was lining up for a shot at goal when he heard someone call out "My old man fucked your mum!" He turned to see that the player who had said it was... his brother Michael, who played for the Lions.
 * According to Ashley Montagu's The Anatomy of Swearing, the phrase "Kwoy inam!" (literally: "Cohabit with thy mother!") is used as a mild diss in the Trobriand Islands. (It's more insulting to tell someone to screw his sister, and even worse to tell him to screw his wife.)
 * This might be Older Than Dirt: A cuneiform tablet from ancient Mesopotamia (ca. 1,500 BC) includes a number of baffling riddles, including:


 * The answer was lost. Perhaps they didn't have enough clay for the complete list.
 * Worth noting, if the answer is:"Me", then this would fall into I Banged Your Mom instead.


 * Hungarian Bishop and poet Janus Pannonius was often teased by other students in Italy for his barbarian heritage. One of his famous retorts would basically come down to "your mother is a bitch". Except it's a latin epigram, written in hexametres.
