Girls Have Cooties

"Jason: (balancing on a brick wall with Marcus) I like to balance like this and imagine there's a pool of lava below. Or a pit of snakes and deadly alligators. Or a... Eileen: Hi guys! Jason: OK, now I'm REALLY scared to fall. Marcus: Does lava burn off cooties?"

- FoxTrot

""No! Girls give me the hives! NOOOO!""

- Chester McBadbat, The Fairly Odd Parents

An absolutely mandatory law (especially prevalent in Sitcoms): If you're male and under 11 years old, you have to automatically think romance and females are gross. No exceptions are allowed. (Except Kidanova, cause that's funny.) Girls of the same age sometimes claim that boys have cooties.

For those of you who were wondering, there are such things as cooties, and they're not limited to girls. "Cooties" just happens to be another word for "body lice."

It should be noted that Cooties is generally only something that happens to girls their own age. It rarely, if ever, affects older girls. In fact, a boy can think that Girls Have Cooties even while having a Precocious Crush on an older girl or woman.

Arguably becoming a Discredited Trope as in Real Life young boys are just as likely to boast about their "girlfriends". This may or may not be due to the increased prominence—compared to a generation ago—of romance and sexuality in entertainment media aimed at or enjoyed by kids. Often leads to jokes about STDs.

If the boy does not get over his dislike of women when he grows up, he might be a He-Man Woman Hater. Compare Allergic to Love.

Anime and Manga

 * Many anime titles tend to avert this, especially those aimed at actual 10-year-olds (and especially if it's aimed at 10-year-old girls). Cardcaptor Sakura is one example.
 * Negi Springfield, the main character of Mahou Sensei Negima, is an aversion. Negi's friend Kotaro, on the other hand, plays this fairly straight (especially the romance thing), with a few exceptions in his adoptive sisters and girls who can fight. That said, he still thinks kissing is gross.
 * Garu from Pucca. Oh, so damn much. Especially after going through Character Exaggeration in the TV series.

Comedy
"I can kiss you! And I can be your girlfriend!"
 * The Frantics sketch "Outgrossing" invovles two boys trying to out-gross each other (turning their eyelids inside-out, etc.). A girl comes along and says she can out-gross them both, which they have a hard time believing - until she describes exactly how.

Comic Books

 * Franklin Richards, Son of a Genius (who must be 6 or something) initially rejects Katie Power (same age) specifically because she has cooties. In a different universe of the multiverse (I think), Katie Power from the future tells Katie Power that Franklin Richards was her first boyfriend; young Katie insists that "boys are gross" but future herself calmly tells her that, in a few years, she'll change her mind.
 * Being a small puppy, Scamp usually doesn't like girls (especially not his sisters), although this varies depending on the writer.
 * Damian Wayne (Batman's biological son) turns up his brattiness Up to Eleven whenever he deals with Batgirl or Supergirl. Both of them are blondes with blue eyes.

Fan Fiction
"The dusty blue-haired boy gave Matsuri a skeptical look, and with great decorum noted, "Icky.""
 * Shutaro from Kyon: Big Damn Hero follows this trope hilariously:

Film

 * The Little Rascals and their "He-Man Woman Haters Club".
 * In the Live Action Adaptation of Speed Racer, Speed's kid brother, Spritle, and his pet chimp, Chim-Chim, break the fourth wall to give a "cooties warning" when Speed and Trixie are about to kiss.
 * Earlier they interrupted a kissing scene and followed up with the classic cootie shot.
 * Little Manhattan has the narrator, Gabe, discussing girls and puberty, mentioning that, once upon a time, word was they gave you cooties.
 * The eponymous eighteen-year old trio in Mystery Team. Jason outgrows this when he meets Kelly, but the others show no signs of progress, going so far as trying to pay strippers to leave them alone.

Literature
"I'm not going to have anything to do with any old girl ever again,' said William. 'It's all very well saying that,' said Douglas, who had been deeply impressed that morning by the inevitability and deadly persistence of the sex, 'it's them what has to do with you.' 'Well, I'm never going to marry any old girl," said William. 'It's all very well saying that,' said Douglas. 'But some old girl is prob'ly going to marry you.'"
 * William Brown in the Just William books can be quite the Kidanova with his chivalrous pining for Girl Next Door Joan and susceptibility to pretty actresses. But Violet Elizabeth Bott leaves him shaken to the core:


 * In Artemis Fowl and the Time Paradox, 10-year-old Artemis says of kissing that you wouldn't catch him wasting time like that. Not as vehement as some of the other examples, but does contain built-in proof he'll grow out of it: Within three years, back in the second book (or at least non-U.S. editions thereof), he's consciously aware that he'll be attracted to Holly when he's older.
 * Erm... did I just read you correctly? The U.S. market required censoring out an internal momentary thought about a hypothetical future physical attraction? Wow.
 * Well, the U.S. publisher, I doubt the actual market would have cared, seeing as how the bit in the spoiler tag happened and the book sold well, but yes, that bit really was removed in U.S. editions of that book. Apparently it got into the U.S. version of the graphic novel, though.
 * The book No Talking by Andrew Clements features an entire group of children who are said to be at the point where they should have gotten over this, but never did. In order to try to prove that one group (either boys or girls) are better than the other, they stage a "no talking" contest. In the end, the group largely learns to shed the "cooties" concept.
 * In The 39 Clues. Dan seems to think this. Example: in Book 5, when he is doing something immature and his sister Amy says something to the effect of, "This is why you'll never have a girlfriend," he replies, "Like I'd want one!"

Newspaper Comics

 * Calvin's GROSS (Get Rid Of Slimy girlS) club.
 * "I know that's redundant but otherwise it doesn't spell anything. Now go away."
 * But "Get Rid Of Girls" does spell something. Just not something he should be thinking about.
 * Calvin also notably attempts to see movies like "Vampire Sorority Babes". He might just be overacting to shut Hobbes up about Susie.
 * Calvin wants to see the movies solely because he knows they are considered "grown up" and "naughty"; he never displays any understanding of why those sorts of movies are considered "grown up" or "naughty". (He once asks Hobbes what "contains adult situations" means; Hobbes says that the movies show people paying bills, going to work, etc., and he's always wondered how movies like that make any money.)
 * Dennis the Menace was once called on this in a late 2007/early 2008 strip, and admits it ... except that he's fine with his mother, Mrs Wilson and the local Tomboy.
 * Jason from FoxTrot is an odd example. He started out firmly in this trope, but a couple of decades of extremely subtle Character Development due to his sorta-friendly relationship with Eileen seems to be weaning him off it. Jason still would rather be caught dead than be known at large as being her friend, but he's not quite so adamantly paranoid about it recently.
 * Marcus, on the other hand, started firmly in the trope, but seems to have thrown it off completely.
 * Averted in the comic strip Heart of the City, where Dean is Heart's best friend and frequent partner-in-crime. He's generally more befuddled by girls than disgusted. (Heart's occasional declarations that Dean's her boyfriend draw a bemused "Um... okay" as often as not.) One New Year's Eve, he actually dressed up in a tux and and announced that to celebrate, "I thought I might hang out with the prettiest girl in Philadelphia." Making it clear that, yes, he meant her.
 * The title character in Agnes has the "boys have cooties" variant, although she still engages in a kind of passive-aggressive flirting with a boy at school named Bob.

Web Original

 * This fake Public Service Announcement raises "cootie awareness" by way of Does This Remind You of Anything?.
 * Before The Nostalgia Critic matured (physically, that is]], he thought girls were loud and annoying.

Real Life

 * Truth in Television for both sexes in many cultures and environments (remember the cootie shots?), but the behavior tends to disappear around fourth grade. The general feeling and how early or late it tends to disappear, however, vary across cultures.
 * Even once it disappears, there's a clear boy/girl divide usually until around the middle of Junior High. Until then, the boys and girls typically sit at seperate lunch tables, engage in seperate activities at Recess, etc.
 * Can be Truth in Television for adult men if you look at it right. Some girls may have "cooties" so always wear a condom. Same goes for girls who want to avoid "guy cooties".
 * An article some years back (no link, sorry) about Tamora Pierce played with this trope with an anecdote about the author's eight-year-old son, an avid reader. It was Mum's job just to bring home the books. At one point, Mum noticed that the pictures on the cover were of girls. Not boys, not animals, girls. She asked his son, "Is this a girl's book?" "No, it's not a girl's book," replies her son with all the scorn of an eight-year-old boy. Then he says, "It's about a girl."
 * Later on in the article, the book's author (Tamora Pierce, of course) mentions that parents have thanked her for including the subject of girls' periods. "Hmm, Mum didn't know that."
 * Cooties are in fact real, they are a slang term for head lice and can be caught from people of the opposite sex.

Webcomics
"thog not scared. nale gave thog booster shot against cooties."
 * Thog from Order of the Stick. Probably an adult, but with the mind of a child.

"Monster: Great! We can start a "No-Eating-Babies" Club! And Tsukiko can't join! O-Chul: Tsukiko Eats Babies?!? Monster: No, silly! She's a girl!"
 * The Monster in the Darkness acts like this as well.

"Loki: It amuses me that your emphasis was on "girl" out of all that."
 * Even demons have fear of cooties in Charby the Vampirate.
 * Played straight as a laser here in Original Life.
 * This Perry Bible Fellowship comic.
 * Original Life did a whole storyline about cooties, starting here, and it's monstrously over the top.
 * Ozy and Millie goes there, too. But not without some fun. Felicia's response to Millie touching her after being 'infested' by boy germs from Ozy? Runs away screaming for various cleaners, culminating with 'Heck, set me on fire!' And you thought it was useless..
 * In The Whiteboard, Jinx would rather kiss a chainsaw than be the possible subject of a crush.
 * In Goblin Hollow, "Girl/boy cooties" causes Lily and Penny to ponder the variable maturity of the goblins.

 * Girl Genius had this mentioned when Vanamonde was surprised that the Heterodyne heir claimant was a girl.
 * Akiko Kitsune in El Goonish Shive was happy that the sister hangs out with a girl because boys are weird and gross. Of course, from this point the situation was bound to get more and more awkward.
 * In Thistil Mistil Kistil, one of Coal's objections to bringing Hedda.

Western Animation
"Hank: Hey there, Bobby. I guess they found a cure for the cooties, huh? Heh heh heh. Bobby: I dunno. What're "cooties"? Hank: Well, when I was a boy, that's what we called the germs you get from girls. Bobby: Oh, you mean like chlamydia? Hank: Huh?"
 * Ben from Ben 10 believes this throughout most of the original series (as he's a teenager in Alien Force, he's outgrown it). He does make an exception for Kai, an Indian girl seen in one episode... but Kai takes his attention and runs with it... to creepy, creepy places.
 * Cooties actually appear as girly butterflies which inhabit DeeDee's bedroom in Dexter's Laboratory. Dexter himself greatly fears them.
 * Inverted in the The Powerpuff Girls episode "Cootie Gras", where our kindergartener heroines are terrified of a boy said to have cooties. Mojo Jojo uses this fact to keep the girls at bay until they get over it. Once they do, however, they leave him Covered in Kisses, then go kick Mojo's butt.
 * Also, used in the first episode featuring the Rowdyruff Boys: The girls' key to defeat them is to look prettily at them and actually kiss them... and it works so well the guys explode in horror. Lampshaded right after this, when Bubbles and Blossom think kissing isn't that bad, but Buttercup is shown coughing and almost throwing up in disgust.
 * Note that in their second appearance this doesn't work, as Him had given them a "cootie shot."
 * The Simpsons, because of Negative Continuity, is all over the place with this one. Bart will go from apparently genuinely thinking girls have cooties, to making out with a girl, and then right back to thinking they have cooties.
 * Subverted on an episode of King of the Hill, when Bobby is invited to a sleepover at a girl (note the space) friend's house:


 * In the Codename: Kids Next Door episode "Operation OUTBREAK", Sector V is sent on a mission to decontaminate the organization's underwater research center from the much-feared Coojatisnal Octo Oogie Terta Infecto Epi Streptacaucus.
 * The South Park kids have managed to maintain this for quite a while, except for Kenny, who appears to have been horny since age 8.
 * Not really; what about Stan and Wendy? Usually the other boys just think it's stupid to be so interested in girls, not bad per se. (This, of course, changes when they get a Girl of the Week.)
 * On The Penguins of Madagascar, the zoo animals see some children talking about cooties and are later convinced that Marlene has caused an outbreak of them after they start getting itchy. Turns out
 * Ed, Edd 'n' Eddy This seems to be one of the main reasons the Eds flee from the Kanker Sisters. This doesn't seem to apply to pretty, girl-next-door Nazz.

Web Animation

 * Women are crazy... for Dr. Tran, who says: "Girls are grody!" This doesn't stop a great deal of "Tran-sexuals".

Video Games

 * Tails of Sonic the Hedgehog thinks this in a few continuities. In Adventures of Sonic the Hedgehog, it's very pronounced. While it comes up less often in the games, it is still there. It actually manages to be a Plot Point.
