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. Especially since a woman who wears army boots these days is much more likely to be in the army.
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."

Issue 611 of ''Amazing Spider-Man'' 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 case anyone's wondering what the blacked-out joke was: "Yo Mama's so old she gave Dracula a reach around."
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.

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:
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!
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.

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.
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. Detecive Lowe:...Dyke.

Peck:HOLD IT! I want this man arrested! Captain, these men are in criminal violation of the Environmental Protection Act, and this explosion is a direct result of it! Egon: YOUR MOTHER... (The rest of what Egon says dissolves into a fist-fight and a rare moment where he expresses actual emotion. It's assumed he said something to the tune of "Your mother's a violation of the EPA")
Major League - Catcher Jake Taylor gets a batter to pop up for a game-ending out with a little impromptu trash-talking along these lines.
Taylor: By the way, saw your wife last night, hell of a dancer, you must be very, very proud. I mean that guy she was with, I'm sure he's a close personal friend and all. But tell me, what was he doing wearing her panties on his head? (Batter Pops Up) Uh-oh, that's it, I don't think this one's got the distance.
Guy: Would that I had known you when you were still capable of making bastards. Godfrey: I knew your mother when she was making hers. Fortunately, you're too old to be one of mine.

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'sAgainst The Day when Archduke Franz Ferdinand of Austria visits a black neighborhood in Chicago in the 1890s.
"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!"
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!"

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?"

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.
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.
Kirk: "What can you expect from a simpering, devil-eared freak whose father was a computer and his mother an encyclopedia."
In the Star Trek: The Next Generation episode The Samaritan Snare, Captain Picard tells the story of how he came to need an artificial heart, by unwisely insulting a group of Nausicans. His recounting of the events included one of these directed at the most fearsome of his opponents—though, Picard being Picard, it's couched in the classiest terms possible:
Picard: I stood toe-to-toe with the worst of the three, and told him what I thought of him, his pals, his planet, and I possibly made some passing reference to his questionable parentage...
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!
Sean Connery: It's been a long time Trebek. Trebek: Not long enough. Sean Connery: That's not what your mother said last night!
Tom Hanks: (hand is stuck in a pickle jar) But I want a pickle. Trebek: But we can't keep playing unless you let go of the pickle. Sean Connery: That's what your mother said last night!

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:
Host: (deadpan) "Yo mama so hairy..." ("T-Dogg" buzzes in) Host: T-Dogg "T-Dogg": Yo mama so hairy, Bigfoot be takin' pictures of her.
Subverted when some of the categories don't lend themselves well to the joke: i.e. "Yo' momma so good at math ..."
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 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.
In "The Vampires of Venice", 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."

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?
In the Stargate SG-1 fifth season episode "Fail Safe", O'Neill and Jackson recount how a particular negotiation with the Asgard went south:
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 Big Bang Theory, Sheldon gets in on the Yo Mama action several times, it's used against him as well.

In S6 E20, Sheldon took the Yo Mama jokes to a new level (for him), saying he banged Raj's mom. This from an asexual virgin.
When the guys fought for a ring from the production of The Lord of the Rings, they tried to get Sheldon down by talking about his mom's sex life. He seemed to be taking it reasonably well, so the guys stepped up and reminded him that his mee-maw had sex to have his mother, but not only that. They bet she also liked it.
Kid: Yes, Ms. Zbornak, what does Joe have to say about all this?
Dorthy: Joe who?
Kid: Joe Mama!

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:
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...
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 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:
Tim Taylor: Your mother is so large, she has her own zip code.
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..."
Barbarino: Hey, say whatever you want about my dad or myself, but you don't talk about my mother! That woman's holy.
M*A*S*H - 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!"

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.

Bob Brown: Tell your mom I'll drop by around 8.

Mulder: Mister Yappi, read this thought. [Yappi stares at him, then suddenly leans back as if he was hit and raises his eyebrow]
"Your mama’s so fat, she could usefully have a calorie-controlled diet and regular exercise."

A sketch on You Can't Do That on Television has the mother walk into the living room, to her child's embarrassment, wearing combat boots. She claims it's (literally) to stamp out cockroaches on the floor.
A quite adorable example from a talkshow on Swedish Television hosted by stand-up comedian Robin Paulsson. The show had pre-recorded sketches starring Paulsson where the humor often rested on him getting things horribly wrong and then digging himself deeper. The relevant example had Paulsson rap-battling in an alley and never once managing to get a boast right or an insult in, in fact just being awkward. In a last-ditch attempt he resorted to the ever-effective Yo Mama strategy. After some rhymes along the lines of "your mom's always kind and helpful", Paulsson looked over his shoulder to find that his homies had left the scene.
Defied in Brooklyn Nine-Nine: Detective Peralta gets into a Volleying Insults match with the obnoxious Fire Marshall Boone.

Peralta: That's not fair!
In ''Veep, Mike and Jonah have this exchange after Mike buys an used car:

Your Mother Should Know by The Beatles becomes hilarious when interpreted as this.
The MC Hawking song "The Dozens".

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

Ridin' on a horse drinkin' whiskey out a boot
She got the wings and the teeth of an african bat
Her middle name is "Mudbone", and on top of all that...
"Shell Shock" by Gym Class Heroes eventually deteriorates into a bunch of Yo Momma jokes (complete with booing), before finally ending with:

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.

"Ah, your mother drinks warm beer!"
One of ventriloquist Jeff Dunham's puppets, José Jalapeño on a Steek has so insulted another puppet, Peanut, this way that it has become something of a Running Gag. For example, this happens when Peanut insults José by calling him a "Mexican condiment":

Qara: What, since your mother lost her job?
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.
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.

Baron Arlange: This is your fault for inviting a stinking turnip in the first place! Your mother would be ashamed!
Duke Prosper: Mmm-hmm-hmm. Says the man whose mother has slept with half of Val Chevin.
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!" note "Chins" is a shortened nickname for chinchompas, a type of grenade weapon used for ranged training. It also means she's fat.
Brassica Prime: Surely the Marimban hosts may have finger-foods and alcohol, but this is clearly the tastiest team to be on. Marimbo: Yeah, if you like bland salads! Brassica Prime: Your mother is a bland salad! Marimbo: Your mother's FACE is a bland salad!
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:
Alfredo: Your mother wears combat slippers! Bill: Leave our mother out of it! Get in the cannon!
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'!"
Asura 1:Your mama's IQ is so low, she thinks "elemental" is four letters in the middle of the alphabet. Asura 2: Your mama's IQ is so low, she thinks a golemancer is what you get when you ask a golemquestion.
Arfenhouse 3 has a boss named "YOMOMMA", who is actually Misteroo's mother. Housemaster laughs at the name.
Phil: My mom just called. Joel: Your mom just called. Phil: ...excellent comeback. Joel: (oblivious) I know.
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.
Joel: Your mom's a world. She's my world. I guess "Your Mom" insults pack less of a punch now.
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 GastonExpy named Brody. It's all quite entertaining, actually...
Frieza Goon A: "Damn man, you couldn't hit the broad side of a space-barn!"
Frieza Goon B: "Yeah well that's only because I'm too busy hitting the broad side of YOUR MOM!"
Cui and Vegeta do this back and forth. Vegeta does it to Cui, who responds that his species reproduces asexually ("Gross. Out of my way"). Cui then does it to Vegeta in the same ep as the first example.
"My mother's dead."
Which is then chillingly referenced by Freeza during his fight with Vegeta:
Freeza: "Well, Vegeta, time to send you crying home to mommy."
Vegeta: (in extreme pain) "My... mother's... dead."
Jon: Imagine the horrors that await you when you go to Horror Land! That's why we're all wearing pointy hats, truly... Chugga: To defend ourselves from Jon's mother! Jon: What?! Am I gonna have to punch you out? Momma said knock you out 'cuz you've called her a whore! Chugga:: I didn't say that! Jon: I'm pretty sure you just did... Chugga: No, I just said she was scary! And... considering how much of a jerk you are, the person who created you... Jon: Okay, I'm gonna throw you out of a fucking window right now.
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:
Yo' mama, is like a brick: she's dirty, she's flat on both sides, AND she always gets laid by Mexicans!
Homestar Runner: 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.
In Arby n the Chief, virtually half of Master Chief's dialogue consists of these:
"You got -3 kills and 31 deaths!" "Your mom got -3 kills in bed last night!"
It's gotten to the point where the Arbiter can anticipate them:
"Yeah, well I found something way moar better. Your m-" "My mom's pussy."
Smosh: Food Battle 2008 had a scene where, when they picked a random item from the catalognote In the Food Battles, the contestants gain points if their favourite food can be used as the item in question, which do not matter because the goal is to kill the other contestant, Anthony suddenly says "How about we do... your mom!". Ian then states that Your Mom jokes are banned in Food Battle 2008, to which Anthony replies by pointing out that there's a picture of Ian's mother in the catalog.
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 whatshesaid! Girl:Yes. Yes, it is.
This extends into the alt-text: "Seriously, it's your mom jokes or me." "Then I, like so many men before me, must reluctantly choose your mom."
Also beautifully subverted in #502. Randall Munroe is a genius for managing to turn a stupid Your Mom joke into a genuine Tear Jerker.
"Your Mother is so fat, she beareth the mark of Chef Boy-Ar-Dee upon her posterior. Oh, snappeth!"
Kiel'ndia in Drowtales uses this against Chiri'nide as they fight  and here, and Chiri being Chiri it works perfectly.
During the gubernatorial debate in Ansem Retort, Zexion used the 'you're a towel' strategy against Cid. Aerith noted it was the rich man's Your Mom joke.
This was Aigis's response to Akihiko as to why she, a robot, couldn't open a door.
Invoked in The Class Menagerie. Tony points out that Brad and Kevin don't like their mothers so they should come up with better insults for each other. They promptly start on "yo' room-mate" insults. Tony is their room-mate.
In this strip of the Dada ComicWitch's Brew, these jokes can become an unstoppable compulsion. (Your Mom is an unstoppable compulsion.) Oh, shut up. (Your Mom should shut up.)
In Pokémon-X, May is being pestered by the NPCs of Dewford, who go on and on about "Invincible Legend" and how awesome it is. Eventually, she snaps and tells one of them that the real big thing is "Your Mother". The NPC takes her at her word, and when Brendan explores the town, he hears everyone talking about "Your Mother" and thinks they're the rudest group of people he's ever met. As the comic writer points out, this is actually possible in the games on which the comic is based.
Something Positive: "Careful about bringing up his mom, PeeJee. He's had a deep-rooted hatred of women ever since he learned she secretly was one."
Becca: I hear a lot of talk, but I don't see a lot of action! Zoe: Your mother doesn't see a lot of action. Bob: Oh, come on now. Fighting is one thing, but mother jokes? Aren't we a little old for that? Zoe: Your mother's a little old for that.
In Captain SNES: The Game Masta, Amon gets enraged when Megaman uses "Your Momma" as an insult. Which is strange, because Amon is a physical incarnation, and doesn't actually have a mother.
Played with in Girls with Slingshots: Hazel asks Jamie who will arrange the upcoming party. When Jamie truthfully responds "Your mom!" Hazel gets it wrong and irritably retorts "YOUR mom!" (The joke is recycled from here.)
In the Space Ghost Coast to Coast episode "Batmantis", Space Ghost discovers that Moltar has been kidnapped by a villain calling herself "Your Mother." Not "Mom," as in the Futurama character, but Your Mother.
Space Ghost: Not my mom, someone else's mom. Someone's sick and deranged mom!
Robot Chicken has a Star Warsskit in which the battle between Palpatine and Luke Skywalker was essentially a game of The Dozens with Star Wars-themed Yo Momma insults.
Luke: Your overconfidence is your weakness. Palpatine: Your faith in your friends is yours! Luke: (mumbling) Heh, faith in yo mama... Palpatine:What was that? Luke: I said, you mama so fat, Jabba the Hut said, "DAAAAAAAAAAAMN!" Palpatine: Well, your mother's so ugly, she put the "Ug" in "Ugnaught"! Vader:(Hood accent) OH, "YOU MAMA" FIGHT! [cue stormtrooper audience, chalkboard, Emcee Vader, and hip-hop version of the Imperial March]
Also, the Rom the Spaceknight vs. Jim the Guy with a Giant Magnet:
Rom: You suck.
Jim: That's what your mom said.
Rom: She did not, my mom was a saint
There's also a man who amuses himself with a pull-and-say children's toy.
The cow says "MOOOOOOOO". *Chuckles and pulls again* Your mom says "Wabglwgaw" because my cock's in her mouth.
South Park made an entire episode of Yo Momma (and Penn State) jokes in "The Poor Kid". No need to guess who on this one.
Principal: "You did a 20-minute song and dance number, with 47 "yo mama's so poor" jokes, followed by a finale with fireworks."
Groundskeeper Willie accidentally pulls one on himself while misreading Bart's lips. "What did you say about me mother?! For your information, her feet stink because she works in manure all day! But it's still the best damn Starbucks in Glasgow!" He apparently reads the same thing from a goat later in the episode.
In "Hell is Other Robots," after Rev. Preacherbot chews out a stoned Bender:
Fry: Who was that guy? Bender: Your mama! Now shut up and drag me to work!
From "Kif Gets Knocked Up a Notch":
Bender: What's this big, ugly thing? A frog? A toad? Or your mama!
From "Obsoletely Fabulous" when Bender escapes the modern world and lives on an island with outdated robots. One of them is a robot who can only talk by inserting cartridges of prerecorded answers.
Bender: A working cartridge unit? Wow, you guys went obsolete years ago. Cartridge unit rummaging through his bag of cartridges, picks out one titled "Snappy response" and inserts it Cartridge unit: Your mother.
Also related is this exchange from "Time Keeps on Slipping":
Leela: I don't know how you did it, Fry, but once again you screwed up. Now all the planets are gonna be cracking wise about our mommas. Hermes: I'm just glad my fat, ugly mama isn't alive to see this. Professor Farnsworth: Enough about your promiscuous mother, Hermes. We've got bigger problems.
Fry inadvertently does it when Zoidberg gives him a physical, asking Fry to open his mouth and say some unintelligible alien phrase. Fry botches it.
Zoidberg: What? My mother was a saint! Get out!
Ren and Stimpy had an episode the twosome was trying to break into a prison and after Ren had a tirade against the warden, he pops from atop the wall, shakes his fist angrily and declares: "Yer momma!" in a completely deadpan way.
In the Hulk episode of Fantastic Four: World's Greatest Heroes, the Thing tries to get Bruce Banner angry by saying "Yer momma's so ugly..." before Bruce tells him that won't work. But when he does change, he goes after Ben for it.
Hansel & Gretel: Ah, your mother rides a vacuum cleaner!
Also used in the 1949 cartoon Paying the Piper where Porky Pig (as the Pied Piper) is frequently insulted in this manner by a cat who's furious that all the rats have been removed from town.
Cat: Ah, your sister smokes corn silk! Porky: My sister doesn't smoke corn silk, she works in a butcher shop and smokes hams! ... Cat: Ah, your brother eats jelly beans! Porky: Gee, I wonder how he knows so much about my family?
At the end of the cartoon, the cat resorts to stealing Porky's reward money to get back at him, but Porky manages to steal the money back and tells the cat "Ah, your father drives a p-p-pickle wagon!"
Bully: Your mother wears army boots! Huey: Uhh, yes!
In Sealab 2021, Quinn uses the "That's what your Momma said" variant on Capt. Shanks in "Let 'Em Eat Corn". When Shanks points out how unoriginal an insult it is, Quinn produces a tape recorder and video evidence; much to Shanks' infuriation, it turns out his Momma really did say that!
In the American Dad! episode "Great Space Roaster", Roger forces the members of the family to insult each other. Steve tells this to Francine: "Mom, you are not smart. I don't tell "yo mama's so dumb" jokes. I tell "my mama's so dumb" jokes.
Also when Bullock is giving a speech at the start of an episode...
Bullock: *a bit of paper flies past* Who threw that?!
Also, at the start of another episode, Dr. Weird tries to convince his assistant Steve to chop off his head, in the hopes that the High-Pressure Blood will propel his corpse "all the way to Phoenix!"
Steve: Uh, what's in Phoenix?
Dr. Weird: Why, it's your momma, Steve! Get the axe!
In "Cybernetic Ghost of Christmas Past from the Future", the titular Ghost tells a rambling story about how Santa Claus originated as a paleolithic ape-man who enslaved alien elves to make toys for early hominid children. When he gets to the part about the elves trying to unionize, Frylock has completely lost the thread of the plot.
Frylock: Wait, who unionized? Cybernetic Ghost of Christmas Past from the Future: Wouldn't you like to know? Probably your momma!
In Regular Show episode "Prank Callers", Mordecai and Rigby prank Pops by asking him to stay on hold for a call from Joe Mama. Of course, this being Pops, he actually stays on hold.
Invoked in another episode where Mordecai confronts Muscle Man over the latter's Catch Phrase "You know who else _____? MY MOM!" He tells Muscle Man that for the joke to work it should be "your mom", then gives three "your mom" jokes as examples. Muscle Man isn't amused.Actually he didn't care and was just messing with them.
In the DuckTales episode "The Robot Robbers" (yes, it was based on a Carl Barks story), Scrooge had Launchpad McQuack flying a helicopter with a banner reading "MA BEAGLE HAS FLEAS!"
In Pinky and the Brain, one of Brain's plans to Take Over the World required Pinky to make him angry in order to transform into a Hyde version of himself. Unfortunately, Pinky had a hard time deliberately making Brain mad:
Pinky: Your mother, she's, uh, older than you!
Home Movies - Jason and Melissa want Brendon to know his mom is becoming a nuisance trying to work her way into the movie they're making - they confront him with "Your mother." He goes "Whoa!...is that like 'Yo mama'?"
Donatello: Hey, Kraang! The one who is called your mother wears the boots that are made for combat!
Metalhead!Kraang: The comment that is made by you shows ignorance of Kraang. The ones known by you as mother-
Donatello: Just come get me!
Stoked: Bummer understands seagull language and says one insulted his mother.
This trope is probably why the phrase "son of a bitch" exists.
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.
In German there is also one: "Fick deine Mutter.".
Or, to make it even a tad more spot-on: "Deine Mudda".
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...
In Modern Hebrew this particular phrase and a ton of other Arabic vulgarities are also commonly used.
An example from... the United States Senate? Yeah, sure, why not.
Jon Kyl (R-AZ): 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. Debbie Stabenow (D-MI): I think your mom probably did.
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:
Glenn McGrath: "Why are you so fat?"
Eddo Brandes: "Because every time I fuck your wife she gives me a biscuit!"
Backfired when Rodney Marsh tried to use the line on Ian Botham:
Marsh: How's your wife and my kids?
Botham: The wife's fine, but the kids are retarded.
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 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.
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"), "la puta que te parió" ("the whore who gave you birth"), 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".
In Spain itself, the Spear Counterpart inversion "Tu padre!" ["Your father!"] is also not unheard of, though it's easy enough to fire back with "Tuyo!" ["Yours!"]
Ironically, although insults like "hijo de puta" or "tu puta madre" are so commonplace in Spain they hardly have any effect, apparently innocuous retorts such as "Tu madre... bien?" ["Is your mother doing fine?"] or "Recuerdos a tu madre" ["Give your mother my regards"] can be a veritable Berserk Button, probably because of the subtle implications.
A common comeback is to say "tu jefa" (literally meaning 'your female boss', actually meaning 'your mom').
The usual way to return an insult or to turn a statement into one is to use "tu abuela" or "su abuela" (your grandmother!). In some places "la tuya que es mi comadre" ("your [mom], my kid's godmother") is used to the same effect.
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 a combination of this trope and Country Matters, the insult "¡el coño de tu madre!" (literally "Your Mom's cunt!") and its abbreviations is the most used insult in Venezuela.
Sometimes it suffices to play the syllable pattern of "itu madre" on your car horn to insult sufficiently.
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 hiswife.)
Hideki Kamiya loves to reply to stupid Twitter questions with "Ask your mom".
In Romania, the expression "Your Mom" , translated as "Mama ta", is sometimes shortened as "ma-ta". An awful lot of people don't actually know that there's a hyphen between "ma" and "ta" in the short form, causing many comedy shows and blogs to compose a song, "Ma-ta are cratima" ("Your mom has a hyphen") to mock the young who "don't even know how to insult each other's mothers correctly."
A subtle example took place during the Fort Lee Lane Closure of '13 when David Wildstein, Director of Interstate Capital Projects for the New Jersey Port Authority, who had ordered the surprise lane closure, said of the local schoolkids, "They are the children of Buono voters." This was an obvious reference to the New Jersey governor's political rival.
