Sometimes people want revenge on someone or to cheat in a contest. One thing they do is just put laxatives in their drink or food. Why laxatives? Because ideally for them one of two things will happen:

# They will suffer a PottyEmergency and forfeit the contest/run away to use the bathroom.
# They will [[PottyFailure soil themselves]] and completely embarrass themselves. Even better if it's in a stadium, especially with something like [[CaughtOnTheJumbotron the Jumbotron]].

In fiction this is normally PlayedForComedy, but occasionally it is {{Deconstructed}} to emphasize the dangerous dehydration element of it.

A frequent variation is using something that induces vomiting rather than defecation.

Note that this is incredibly illegal and risky in real life. The victim could end up seriously ill, hospitalised or worse. Dehydration is also not the only risk: the person could be allergic to the laxative or its inert ingredients, or could even suffer a RupturedAppendix or internal bleeding. The induced vomiting variant can cause internal bleeding, and is actually far more likely to do so than a laxative. Consequently, administering even such a seemingly-trivial pharmaceutical drug to someone without their knowledge is classified as a serious criminal offense in many jurisdictions-- the perpetrator of the prank could wind up in jail.

There is also a variation involving over the counter eyedrops that ostensibly have the same effect. This is even more dangerous as ingestion of the active ingredient in the drops can cause a range of dangerous symptoms up to and including sending the victim into a ''coma,'' with diarrhea being the ''least'' likely symptom.

[[folder:{{Anime}} & {{Manga}}]]
* ''Manga/FutabaKunChange'' In a beauty contest, TheRival puts laxatives in a tea given to the heroine to calm her. Unfortunately for the rival, some of the other contestants drink it to annoy her. HilarityEnsues, [[PottyFailure and you can guess happens after they drink it.]]
** Earlier in the series, an extremely underhanded character uses a batch of spiked drinks clear the field in the completely ludicrous MartialArtsAndCrafts tournament held to determine what club the heroine would join.
* In ''Manga/DragonBall'', Bulma does this to Oolong when he refuses to cooperate with her in helping find the Ox-king. She gives him a candy that he thinks is delicious, but really it's a laxative, and every time she whistles (or yells "piggy", in the English dub), he will have an emergency. Goku takes advantage of it to manipulate Oolong, too.
** In a filler episode, Goku is given laced food so he would lose in a tournament, the laxative takes effect in the middle of the fight but Goku manages to defeat his opponent before running away desperately.
* In the Cotton Drifting arc of ''VisualNovel/HigurashiNoNakuKoroNi'', Satoko uses this as part of an elaborate prank against some punks who are trying to take advantage of [[FanNickname Shmion]] during the Angel Mort dessert fest.

* Attempted by the King and Rosario in ''DragonHalf'' to get Mink out of the tournament, in the form of an "energy drink." {{Lampshaded}} by Mink's friends, but ignored by Mink... who then proceeds to give it to Dick Saucer, who is thus unwittingly victim to this (and who blames Mink for it, naturally).
* ''Manga/GambleFish'' has [[spoiler:the character Tsukiyono]] getting a cow laxative put in her drink, so the main character has no help in the tournament.
* In ''Manga/HunterXHunter'', [[TheMillstone Tonpa]] tries to get several characters to forfeit the Hunter's Exam by offering them laxative-spiked juice. It utterly fails, as [[ProfessionalKiller Killua]] has AcquiredPoisonImmunity, [[NatureHero Gon]] immediately spits the juice out when he notices that it tastes weird (despite the drug being odorless and tasteless), and everyone else either refuses the drink outright or gets rid of it once they see Gon's reaction.
* In the ''Manga/BlackButler'' manga, Ciel has Sebastian slip laxatives into a meat pie and feed it to the opposing team before a cricket match.
[[/folder]]

[[folder:{{Film}} - Animated]]

-->'''Kent Mansley:''' No, knock yourself out, skipper.
-->'''Hogarth Hughes:''' ''(crumbles up laxative)'' You crumble up the chocolate into little pieces. ''(stirs the ice cream)'' Then you kind of just stir it into the ice cream. See?
-->'''Kent Mansley:''' Yes, I see. What do you call this again?
-->'''Hogarth Hughes:''' [[MeaningfulName Landslide.]] It's new. Very new.

-->'''Richard Bagg''' "I'm bleeding!"
* This is one of the ways the ''ThreeNinjas'' defend themselves against a trio of bumbling kidnappers. Not exactly what you expect from "ninjas," but this is an early 90s kids' movie, so there we are.
** Then again, ninjas were historically known for [[CombatPragmatist Combat Pragmatism]].
* In ''MajorPayne,'' the recruits try to do this with Payne's cupcake. [[spoiler:It backfires. [[{{Fartillery}} Literally.]]]]

* In ''Discworld/TheAmazingMauriceAndHisEducatedRodents'', Malicia puts laxative powder in the Rat Catchers' tea, then tells them they've been poisoned and holds the antidote hostage until they do as she says. [[spoiler: The "antidote" [[FromBadToWorse is laxative powder too]].]]
* In [[Film/AChristmasStory Jean Shepherd's]] short story "A Fistful of Fig Newtons", originally published in ''{{Playboy}}'', a scrawny college student challenges a BigEater football player and several fellow college students to a laxative-off.

The Big Eater figured he'd have no problem, but he ended up heaving half his insides out while the little guy wins, having built up an immunity in the past.
* The Russian book ''The Poisoning'' has a pharmacist do this to save the life of their friend. To explain, a pair of StarCrossedLovers were planning to commit suicide together, and the girl was trying to buy sleeping pills pretending they were to sleep better. The suspicious pharmacist replaced them with laxatives instead, and the suicide went... unexpectedly. Both survived, though in agony.
* In his short story "The Fly", humorist Creator/PatrickMcManus tells of being a night janitor in college, and the steps that the department secretaries took to keep the janitors from pilfering their desk goodies:
-->"A secretary over in Sociology loaded a massive charge of chocolate-flavored laxative into a choice morsel and almost wiped out Charlie Fisk."
-->"That's terrible," I said.
-->"Yeah. And poor Charlie wasn't even the one who ate it. He was just an innocent bystander."
* Played straight in Creator/CharlesStross' ''[[{{Accelerando}} Glasshouse]]'': Reeve spikes Fiore's coffee to give herself time to take an impression of his key to the special room in the library.
* An apparently rare serious use of this in ''Literature/TheRegulators'', by StephenKing (under the Richard Bachman pen name). Seems Tak doesn't like being in a host body while that body is defecating, [[spoiler:so Seth gets Audrey to put Ex-Lax in his chocolate milk to get Tak out of him long enough to carry out his plan to permanently solve that problem]].
* In the VCAndrews book Dark Angel, Heaven's RichBitch classmates spike her punch with a laxative, then ask every boy present at the party to dance with her--ensuring that she can't get away--then locking all bathroom doors. She's able to relieve herself in a garbage can, then dumps the waste bag down a laundry chute, and managers to entice the cloudless AlphaBitch leader into going down the chute (daring her to prove that she's brave enough to do it), thus doling out some severe LaserGuidedKarma. There's a darker example in a later book in the series, where Heaven's daughter Annie has been paralyzed. Her sadistic nurse spikes her food with a laxative, then refuses to help her when she soils herself (angry when Annie refused to eat the food she prepared and asked for something else).
* ''The Bloody Road To Death'' by SvenHassel. Black marketeer Joseph Porta thinks it's his lucky day when an English parachute drop containing Darjeeling Tea falls from the sky, so he sells it to the German General Staff. Unfortunately the nefarious British have put a strong laxative in the tea.

To help a student who was being bullied, they prepared an laxative brownie, knowing the bully would take it from the kid and eat it.

LarryTheCableGuy then pipes up that he's been on both sides of that particular prank.
** Not exactly a prank, but Jeff also had a bit that mentioned how, when he turned 50, he had to have his first colonoscopy, and how the prep for the procedure is to take a sizable amount of laxatives in order to clean out your system for the camera. Since he was goofing off during the consultation, he didn't hear the doctor say you're supposed to take them over a period of four hours, and instead took all of them in less than ten minutes. He said his gut started to sound like the house in The Amityville Horror.

[[folder:Video Games]]
* Required in ''{{Enhanced}}''.

The title characters and their friends agree to spare TheSociopath Cyndi's reputation if she helps them humiliate the bully ringleader Karen by spiking the alcohol popsicles at her party with toothpaste, to make them taste bad. Instead, Cyndi spikes them with laxative. While most of the party guests undergo minor, though embarrassing and uncomfortable, [[PottyEmergency potty emergencies]], Samantha consumes enough spiked popsicles to necessitate a trip to the emergency room.
* Sgt. Coffman of ''Webcomic/AirForceBlues'' does this to Capt. Dahl's coffee on a daily basis. Lt. Willows develops a taste for it after losing several pounds when she accidentally drank a cup.
** Coffman also denies using eyedrops for this, saying they cost too much to waste on a prank ($30 for a very small bottle). Ex-lax, on the other hand....

Cartman's plan backfires when the [[PottyFailure obvious]] ensues, and Jenny ends up attempting suicide. Cartman's way of fixing everything? So nobody gets singled out, the staff and Cartman attempt to give the students laced Pizza Hut pizza, so everyone will crap themselves.

[[folder:Real Life]]
* A far darker version of this is used as a combination of torture and execution method [[BuryYourGays against gay men]] in some regions of the world - the anus is glued shut or otherwise obstructed, and overdose amounts of strong laxatives are administered. The result is an agonizing death by intestinal rupture.
* Creator/AlfredHitchcock did this to one of his cameramen in RealLife.
* The vomiting variant of this (as well as its use in the eating disorder bulimia) is why syrup of ipecac is no longer produced or sold at least in the US. Originally intended as a poisoning antidote, ipecac turned out to be almost worse than useless for that, and unfortunately very useful to bulimics and pranksters. The only problems were that ipecac itself was cardiotoxic, and the vomiting it induced was often so violent it ''frequently'' produced [[https://www.nlm.nih.gov/medlineplus/ency/article/000269.htm Mallory-Weiss tears]] with severe internal bleeding as the result. Ipecac got removed from the market around 2009, none too soon.
* This is actually what got the Creator/MarquisDeSade sent to prison. He was trying to get prostitutes to fart on him, messed up the dose, and poisoned the women.
* This happened to Creator/JohnBarrowman back when he was doing musical theater in Nashville. His understudy [[http://www.youtube.com/watch?v=PihAzHEcehw spiked his drinking water]] before he went out on stage. Where he had to sing and dance. In white polyester.
