This trope is pretty straight forward. A character receives some sort of trauma to their backside. As mentioned above this trope often appears in slapstick or otherwise humorous context. This is because in addition to the fact that butts, particularly large ones, are often seen as inherently humorous and because butts are naturally padded if something or someone strikes it there's less likely to be any serious injury involved.
This tends to happen to plumper characters more often since their butts are naturally bigger targets.
A super trope to Rump Roast, Butt Biter, Literal Ass-Kicking, Anal Probing, Thumbtack on the Chair, Shot in the Ass, Ass Shove Comedic Spanking, and Butt Brand. Contrast Butt Sticker and Ass Kicks You, where it's the butt that hurts someone else.
- The page image is from Disney's Hercules, where the introduction to Pain and Panic has the two bumbling henchmen tripping down a flight of stairs and Pain landing bottom first onto Panic's horns.
- Lampshaded in Disney's Moana. Maui is in the middle of a "The Reason You Suck" Speech to Moana, while denying her the ability to sail the boat they are both on. Moana just takes it, but the Ocean intervenes by sticking a blowdart (from an earlier encounter) into Maui's backside, paralyzing him. Moana then takes control of the boat. (It makes way more sense in context.)
Maui: Blowdart. In my buttcheek. You are a bad, bad person.
- In Shrek, after a fight with Robin Hood and his Merry Men, Shrek ends up with an arrow in his butt. He doesn't even notice it until Fiona points it out and removes it.
- In The Rescuers, Luke uses his pitchfork to prod Madame Medusa in the butt.
- In The Lion King, "I Just Can't Wait to Be King" ends with an elephant falling on an antelope's horns butt-first, eliciting a pain-induced Wild Take.
- In Cinderella, Gus ties his tail to the spout of a teapot and tries to reach for the key to Cinderella's room, which Jaq is handing to him from the stepmother's pocket. However, the pot tips and a drop of piping hot tea drips onto Gus' bottom, causing both mice and the key to fall onto the villain's dress and slide safely onto the floor.
- In the prologue of City Slickers, the three main characters are in Spain for the Running of the Bulls. The segment concludes with Billy Crystal's character Mitch getting gored in the behind.
- In Smokin' Aces, Jeeves Tremor is killed when Sir Ivy forces him to sit down on his running chainsaw.
- Space Jam: During the Tune Squad's retaliation against the Monstars, Daffy Duck paints the ass of one of their members red. Toro the Bull is in the audience. You do the math.
- The Parasol Protectorate: Although details are somewhat lacking, the first meeting between Alexia Tarabotti and Lord Conall Maccon involved the latter accidentally sitting on a hedgehog, which Alexia insists she didn't deliberately leave on a chair.
- The Back Story of Bit Character Merrett Frey from A Song of Ice and Fire includes being captured by an infamous outlaw band, (think a major deconstruction/Darker and Edgier version of Robin Hood and his Merry Men) and a female member of the outlaws branded him on the ass during his captivity.
- A mini-arc in Everybody Loves Raymond featured Robert's injury in the line of duty when he was gored in the Upper Thigh Region by a bull that escaped from an illegal rodeo. Certainly made for a memorable arc because of the nature of how a police officer was downed and partially the embarrassment Robert faced when it was revealed that the by-standard footage went viral.
- Shakespeare & Hathaway - Private Investigators: In "Exit, Pursued by a Bear", Frank is interviewing a suspect when he sits down heavily on a pin cushion and jumps immediately to his feet. The pincushion later turns out to be a vital clue in solving the mystery.
- This comedy mechanism has been discussed in the Big Cartoon Forum, here: . Granted, it's all Western Animation stuff, but posteriors get poked nonetheless.
- Ren & Stimpy has featured a couple of examples in their time usually happening to Stimpy (one of the perils of having a big butt). One unique one is from the Christmas special when Stimpy tries to fart for Ren. Stimpy's butt cheeks strain so hard they actually wind up deflating like a couple of balloons. Then Ren kicks at the deflated remains.
- Loonatics Unleashed has on three separate occasions delivered a low-level psionic zap to Danger Duck's tail, each time in response to some calumny uttered by Duck. It's a superpowered equivalent of a spank upon rude youngster. "Hey! Easy on the tail feathers!"
- When the villain captures the dune buggy of Josie and the Pussycats with a claw lowered from a helicopter, Alan, Josie and Alexandra fall out of the vehicle onto the ground. Alan and Josie are fine, but Alexandra, as the Token Evil Teammate and Butt-Monkey of the group, finds herself sitting on a cactus. The Team Pet Sebastian amuses himself by extracting the needles from Alexandra's tender tissues.
- In fact, throughout the series, whether it's getting poked in the rear by a drill, landing ass-first on a cactus, or getting her butt cheeks pinched by a crab or claw, Alexandra tends to receive a lot of rump-targeted pain.
- This happens to Dick Dastardly as well in Wacky Races when one of his plans to stop the other racers ends up with him in a bushel of cacti. Muttley uses a wrench to pluck the needles from Dastardly's keister.
Dastardly: And remember...you're not plucking a chicken!
- Disney's theatrical short cartoons seemed unusually interested in Walt's cartoon animals' rear ends—and in particular, administering physical punishment to them when their owner is incapable of escape:
- In The Band Concert (1935), a passing tornado leaves Donald Duck trapped between two intertwined trees, his arms, legs, and head facing one direction and his butt prominently pointed in the other. The tornado sends the band members, their instruments and assorted debris spinning in the air, and a particularly obese pigs butt sliding along a picket fence, breaking off their pointed tops as he goes.
- In The Practical Pig(1939), the titular character catches his brothers lying. His elaborate mechanical lie detector scoops them up, firmly straps them in butt-upwards and paddles their exposed fannies glowing red. Earlier in the cartoon, the camera (viewing from a low angle that suggests its eavesdropping on them) lingers on their butts as they squeeze into tight bathing trunks. (The shot is particularly curious in the fact they normally run about bare-assed to begin with.)
- Donald Duck seemed particularly prone to wind up in this sort of situation. In Modern Inventions (1937) an automated barbers chair turns Donald upside-down, ties a towel around his feathery fanny and tries to give his tail feathers an unwanted trim.
- In Window Cleaners (1940), while being hoisted upwards on a scaffold, Donalds tail feathers are clipped clean off by someone trimming their window plants, leaving the tip of his tail pink and featherless. (His feathers replenish themselves by the following shot.) The entire last half of the eight-minute cartoon is devoted to Donalds battle with a bumble bee that culminates with the duck completely tangled in the scaffolds ropes, his butt fully exposed to the vengeful bee. The bee, himself exhausted by the battle, slowly summons his remaining energy to attack the helpless duck, allowing Donald plenty of time to fearfully await his impending punishment.
