Western Animation: The Day My Butt Went Psycho

Butts: always one step behind. Years ago, butts rose up to overthrow humanity. But humans fought back, and now an uneasy peace remains as the world waits for the next great buttfighter!

Based on the grossout book of the same name, The Day My Butt Went Psycho! follows Zack Freeman, his butt Deuce, and their friend Elanor Stern, daughter of legendary buttfighter Silus Stern, as they battle the Great White Butt and his henchmen, the Prince and Maurice - at least, when the three of them aren't busy doing something non-villainous - prove just how awesome (or lame) they are as buttfighters, and otherwise have all sorts of misadventures. Along the way, they'll lampshade a ton of tropes, frequently lean on the fourth wall, and settle into an interesting hybrid between John Kricfalusi's art style and more traditional "on-model" shows, dropping all sorts of butt and bathroom puns just because they can.

Tropes that apply to this show:

  • The Ace:
    • Silus Stern is, hands-down, the greatest living buttfighter, and his team from the Butt Wars, the B-Team, is close behind him in skill.
    • Gran Freeman also qualifies, given her secret identity as the Pincher.
  • Androcles' Lion: Subverted in the episode Legend of the Butt-Squatch when Zack removes a giant splinter from the titular Butt-Squatch's back - only for the beast to unfurl it's previously-stuck wings and eat Zack as well as Deuce and Elanor, who tagged along to find the creature.
  • Always Someone Better:
    • Given how Elanor is just plain better at buttfighting than Zack, this is a frequent reason behind Zack's buttfighting challenges to Elanor. While Zack frequently loses, something always happens afterwards which allows him to prove himself anyways.
    • An entire episode revolves around Zach attempting to defy this when discovers he's dead last in Buttfighter Monthly's Top 100 Buttfighters list - literally losing 99th place to a twig - by becoming the owner of an ice cream shop, a field where he's sure he'll be the best.
  • Anime Hair: Zack, whose hair extends a ludicrous distance forward from his head. Lampshaded by Silus, who occasionally refers to him as "the boy with weird hair".
  • Badass: If the fact that even the most inexperienced buttfighters shown in the show are capable of taking on the Great White Butt's army of robo-butts is any indication, this is a prerequisite for being a buttfighter.
  • Badass Grandma: Gran Freeman, aka The Pincher, a buttfighter on par with Silus Stern.
  • Be Careful What You Wish For: When Zack, Elanor, and Deuce wish Gran Freeman's butt, a Drill Sergeant Nasty par excellence, would loosen up so they can watch the evening's Bummy Rippa marathon, Zack and Deuce find a way to give them their wish by transforming Gran Freeman's butt into a fun-loving butt. However, Gran's butt immediately organizes a massive party which not only prevents them from watching the marathon, but also causes Deuce to go buttserk and destroy the house.
  • City of Adventure: Mabeltown is this, what with it being home to the greatest living buttfighters and the mortal enemy of human and buttkind.
  • Drill Sergeant Nasty: Gran Freeman's butt is revealed to be this when she is left to babysit Zack and Deuce in her first appearance. However, she ceases exhibiting this trope in subsequent episodes because the duo transform her into a fun-loving butt in the same episode.
  • Endangered Soufflé: Lampshaded in one episode when Deuce and Elanor's fighting is wrecking everything Zack does. He comments that he probably picked the wrong day to bake a souffle. Just as he takes it out of the oven, Deuce and Elanor thunder past. Miraculously, the souffle survives. Then Deuce returns to shout (through a meagphone) how amazing it is that the souffle didn't collapse...
  • Foil: Jonas to Elanor Stern. He's spoiled rich, brags about the fact his father's money can buy him almost anything, and has absolutely no empathy towards anyone; in contrast, Elanor, while also rich, doesn't brag about her wealth, is best friends with Zack and Deuce, frequently has them over to her house, and otherwise chooses to live a normal life when not training to be a buttfighter.
  • Go-Karting with Bowser: Just as frequently as Villains Out Shopping, once Zack and company realize the villains (usually the Great White Butt and his henchmen) are actually being sincere, they'll happily let them join in on whatever they're doing - usually because they don't want the villains to have gloating rights.
  • Gem-Encrusted: Silus Stern's toilet.
  • Grossout Show
  • Life of the Party: This is what Gran Freeman's butt transforms into when Zack and Deuce introduce her to "fun".
  • Long-Lost Relative: This version of Elanor actually has a butt name Smellanor who ran away from home at birth because she thought Silus, who was merely bringing his new-born baby girl and her butt home, had kidnapped her from the hospital. Too bad she's evil and has Elanor brainwashed.
  • Mad Scientist:
    • Silus is revealed to be this (among many other things) in Season 2, having built such inventions as a toaster which can be set to cause a deadly earthquake.
    • Elanor has demonstrated shades of this, having developed in Season 1 a highly-experimental artificial butt re-oderizor which restores the stink shield of any butt whose human is stupid enough to wash them - albeit with nasty side-effects.
  • Master of Disguise: In one episode, Zack, Deuce, and Elanor challenge each other to a disguise-off to see who can most effectively con their way into the Buttfighter's Ball. Zack's disguises fool no-one except Deuce, Elanor's disguise is flawless (it does help her dad has a computerized tailor), and Deuce, too lazy to make a disguise, sneaks in by hiding in a tray carried by one of the robo-butts catering the event.
  • Meaningful Name: The members of Silus Stern's B-Team describe their fighting technique; for example, the Kisser attacks using kisses, the Smacker attacks with her fists, and so on.
  • Missing Mom: Like Zack's parents, Elanor's mom is never mentioned nor seen in the show, likely due to the fact she's dead in the source material and nobody dies in the show.
  • Non-Lethal Warfare: Combat in the show involves plunger guns, Gatling toilet paper guns, stink bombs, and other such weapons befitting the show's toilet humor.
  • Only Sane Man: Elanor is a female version of this in comparison to Zack and Deuce (especially Deuce), frequently facepalming at the many insane schemes the two have concocted over the course of the series. She increasingly becomes this in comparison to her father in Season 2, where his otherwise-average intelligence begins to decline to the same levels as Zack.
  • Parental Abandonment: Zack's parents are never mentioned nor seen in the show, effectively resulting in him and Deuce being raised by his grandmother. However, unlike Elanor's mom, Zack's parents are alive and well as buttfighters in the source novels, making this an odd example.
  • Nobody Can Die: One of the ways the show is lighter and softer than its source material.
  • Non-Idle Rich: Elanor and Silus Stern, believe it or not.
  • One of the Boys: Elanor is almost always seen hanging out with Zack and Deuce and doing the things they do (usually so long as they aren't especially stupid things).
  • Lighter and Softer: Unlike the works which it's based on, no-one dies and the main villains are far sillier, being content with conquering Mabeltown instead of destroying humanity. However, this also causes some weird problems plot-wise (see Missing Mom and Parental Abandonment).
  • Punny Name: A regular occurrence with episode names, which usually make some sort of butt-related pun on a pre-existing work's title. Examples include The Flushinator, All's Smell That Ends Smell, and Journey to the Center of Mabeltown Crack.
  • Real Women Don't Wear Dresses: This is Elanor's in-universe reaction to girly-girl Chelsea and her cheerleading squad, who, despite their outward appearance, are more than capable of fighting off the Great White Butt and his henchmen and chucking full-size furniture through a third-story window.
  • "Rear Window" Homage: The episode Cheer Window is this, with Elanor as L. B. Jeffries, cheerleader Chelsea as Lars Thorwald, and Zack and Deuce as Lisa Carol Fremont and Stella, respectively. However, instead of Chelsea being wrongfully accused by Elanor of murdering someone, she's wrongfully accused of helping the Great White Butt take over Mabletown. He just wants to learn cheerleading.
  • Spoiled Brat: Jonas, who lives next door to Zack, can get almost anything he wants, whether it be through his father's outrageous wealth or his robo-buttler, and rubs it in everyone's face.
  • ¡Three Amigos!: Zack, Deuce, and Elanor form such a group, with Zack being the Idiot Hero, Deuce being The Fool, and Elanor being the Only Sane Woman.
  • Toilet Humor: If the fact that people's butts are sentient and can detach from people's bodies doesn't clue you in, go watch the show. It revels in it.
  • Toothbrush Floor Scrubbing: Gran Freeman's butt makes Zack and Deuce do this when she is left to babysit. [[Squick Deuce uses Zack's toothbrush]].
  • Villains Out Shopping: When they aren't trying to destroy or conquer Mabeltown, the villains, specifically the Great White Butt and his cronies, will be out doing mundane things, like eating burgers, organizing birthday parties, or learning to be cheerleaders, without displaying any malice towards the town, its populace, or their arch-nemeses. Despite how frequent the villains do this, though, Zack and company usually don't believe them; how much convincing it takes them to change their minds varies by episode.
  • You Gotta Have Blue Hair: Zack actually has blue hair.
  • Wholesome Crossdresser: Silus occasionally dabbles in this, best demonstrated when he wore a very girly pink dress for the Buttfighter's Ball.
  • Write Back to the Future: In The Flushinator, Zack, currently trying to stop an Expy of the Terminator writes a message in wet cement, asking his future self to travel back in time and hide a futuristic freeze ray in the bushes beside the sidewalk. He then reaches into the bushes and finds the freeze ray there.
  • Wrong Parachute Gag: In Flush of Dooty, Deuce opens his parachute for nothing but a stack of cheek burgers to come flying out.
