->'''Garth:''' Wayne, what do you do when, every time you see a really hot girl, you feel like you're going to hurl?
->'''Wayne:''' I say hurl. If you spew and she comes back, she's yours. But if you blow chunks and she bolts, it was never meant to be.
-->-- Pearls of wisdom from ''Film/WaynesWorld''

Exaggeration of the nervousness and discomfort one feels at approaching someone cute to the point that they become physically sick (major turnoff). If the character is lucky, they might find the one person who doesn't trigger the reaction. Compare CannotTalkToWomen, LoveMakesYouCrazy, DoesNotLikeMen ([[HeManWomanHater or women]]), ParalyzingFearOfSexuality and ChasteHero.

Oddly, this is not automatically a [[ComedyTropes Comedy Trope]]. Or an anime trope, but it's used far more there.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* Xellos from ''Anime/{{Slayers}}'' is allergic to, in addition to love, any and all positive emotions.
* ''Manga/AhMyGoddess'': Keiichi tries to ask Belldandy out to a museum, and gets so nervous that she immediately diagnoses him with a terrible illness. [[HilarityEnsues And acts accordingly.]]
* Alex Treveney from ''Manga/{{Nightschool}}: The Weirn Books''. If she says that she likes or loves something, it will explode.
* Sunako from ''Manga/YamatoNadeshikoShichiHenge''. She completely freaks out, nosebleeds to the point of hemorrhage and passes out whenever she sees "bright creatures." In a slight subversion, this applies to females as well as males, but is usually centered on her {{Bishounen}}...housemates.
* Junta, the lead from ''Manga/DNA2'', vomits uncontrollably around ''any'' girl that arouse him, not just his love interest.
* ''Manga/GirlsBravo''
** Yukinari has literal allergies to girls, vaguely explained as being a victim of bullying.
** It also turns out that the BigBad ''is'' the BigBad because [[spoiler:she's allergic to boys.]]
* ''Anime/HanaukyoMaidTai''. In the first series Taro changed colors and sometimes collapsed whenever women (except Mariel) touched him.. This was toned down in the show's remake, probably because he literally had no other problems interacting with girls.
* ''Franchise/SailorMoon'''s Ami, along with other much more extreme and neurotic behaviors, reacts to getting a love letter by breaking out in ''hives'' in "Ami-chan's First Love," a [[Manga/SailorMoon manga]] side-story adapted into an animated short preceding the ''[=SuperS=]'' NonSerialMovie. The short film version creates an AdaptationInducedPlothole, as the original [[Anime/SailorMoon anime]]'s continuity saw her in a relationship with CanonForeigner Ryo Urawa, with no previous indication of a love phobia.
* The lead of the manga series ''GirlsSaurus'' and it's sequel ''Girls Saurus DX'' is a "healthy" young boy... until he receives a beating from an [[{{Gonk}} overweight high school girl]], severe enough to send him to the hospital for a few weeks; afterward he develops gynophobia, and has an [[TheUnwantedHarem unwanted harem]] form around him. HilarityEnsues.
* The ''LightNovel/DirtyPair'' have played bodyguard to boys with allergies to women ''twice'' (once on the TV series, once in ''DP Flash''). Both boys were also extremely rich. HilarityEnsues, of course.
* Rito of ToLoveRu was sort of like this. He was less allergic to love/girls, and more shy of physical contact to the point he would run if he could. One of the major over-arcing elements of the plot is him getting what could be compared to immersion therapy throughout the manga.
* In the early episodes of ''{{Dragonball}}'' the tough guy Yamucha is severely gynophobic, and intends to use the dragonballs to wish away his affliction.
** [[spoiler: He doesn't get his wish, but he eventually gets cured when he realizes he just has to become familiar with a woman.]]
* In ''Manga/MahouSenseiNegima'', Nodoka starts out this way - she can't stand being anywhere near a man, seemingly becoming downright terrified just by the thought, and physically recoiling at the sight of a BoysLove manga. Since she goes to an all-girl school, she can usually avoid such contact, but her friends warn her that once she leaves the school, half the world is men... and fortunately, [[AdorablyPrecociousChild Negi]] is just what she needs to get over her fears.
** In the original manga, she's just a typical ShrinkingViolet.
* In the manga ''Manga/ZodiacPI'', the smart, cool, and aloof Hiromi breaks out in a rash whenever a girl, even his sister, touches him, owing to a love letter gone badly as a child. He gets over it.
* Hinata from ''Manga/{{Naruto}}'' has some extreme reactions when in the presence of the only guy she loves, Naruto. It gets less severe over time until [[spoiler:she finally confesses her love to him]].
** In reality she never really acts all that odd toward Naruto in the manga. The anime takes a few outlying examples of her behavior [[NeverLiveItDown and makes it a key part of her characterization]].
* While Daisuke from ''DNAngel'' doesn't get ill when he's around his love interest, experiencing the feelings of love sets off an "genetic condition" that [[ThePowerOfLove turns him into]] his alter ego, PhantomThief Dark. This leads to Daisuke constantly running away from the girl he has a crush on.
* Naeka of ''Manga/KamenNoMaidGuy'' is like this initially, due to the fact that her LethalChef tendencies caused to her accidentally poison her first crush. She gets over it, with some help from Fubuki. The whole thing then backfires spectacularly when she finds out [[spoiler: that her secret admirer is a girl.]]
* Inverted in ''Manga/MariaHolic''. The protagonist is a [[SchoolgirlLesbians lesbian]] but breaks out in hives whenever she's touched by a boy. HilarityEnsues, being that the antagonist is a cross-dressing boy.
* Fuko in ''Manga/{{Gilgamesh}}'' sneezes when in proximity to her (current) crush.
* Yukina in ''Manga/SeraphimCall'' passes out whenever confronted by men (even over the vidphone). It is so bad that she lives in isolation, and wears a special suit that inflates as a cushion whenever she is passing out.
* Shogo from ''Manga/ApollosSong'' might count, except his reaction is "violent revulsion and pathological hatred" instead of "fear".
* ''Manga/OuranHighSchoolHostClub'''s Haruhi has this affliction in the manga for a brief period of time. She has all these 'symptoms' such as heart palpitations and feeling feverish around Tamaki after he had opened up to her more about his past and then kissed her on the head when he left. She thinks she has some sort of illness or that her heart is rejecting her. She got better a chapter or two later.
* The protagonist Tachibana Rintaro has a disease where if he sees anything related to {{Fanservice}}, his illness would go bad and if he gets too much, he'll die.
* In ''Franchise/OnePiece'', this is ''literally'' the reason why several empresses of the Kuja Tribe on Amazon Lily died of illness; they all contracted "Love Sickness" by falling in love with a man and died of "Love Burn" due to being unable to pursue their object of affection since men are forbidden on Amazon Lily. The only reason why Elder Nyon managed to survive is because she left the island. Hence, [[WorldsMostBeautifulWoman Boa Hancock]] contracted the disease when she fell in love with Luffy and was only cured when she aided him [[spoiler:in his attempt to rescue Ace.]]
[[/folder]]

[[folder:Fanfiction]]
* [[KingdomHearts Sora]] in [[http://www.fanfiction.net/s/7262795/1/Love-Sick Love Sick]] violently throws up even if he just SEES a girl. It varies, though, depending on age (girls closest to his age do the worst) and appearance (one girl looked so much like a guy he was unaffected until he realized "he" was a "she"). Kairi is labeled as the most dangerous girl he's ever encountered thanks to just a '''glance''' at hear causing the most violent reactions in his '''life'''.
[[/folder]]

[[folder:Film]]
* The protagonist of ''Film/{{Adam}}'' finds it very difficult to talk to the female lead because of his Aspergers.
* Invoked in ''Film/TheLittleRascals'', when the members of the He-Man Woman Hater's Club recite a pledge which describes the penalty for [[GirlsHaveCooties falling in love]] as "May I die slowly and painfully and suffer for hours or until I scream bloody murder."
[[/folder]]

[[folder:Literature]]
* In JimButcher's ''Literature/TheDresdenFiles'', the [[OurVampiresAreDifferent White Court vampires]] of House Raith feed on sexual desire, but a person touched by true love can burn them like sunlight burns a movie vampire. The relationship between Thomas and his favorite toy, Justine, has slowly progressed from "mutually beneficial experience" (she gives him nourishment, he keeps her mental illness in order) in ''Grave Peril'' to "true love" in ''Blood Rites''. It can't end well.
** However, it only applies when the last person somebody was intimate with loved and was loved by them. As of Ghost Story, Thomas and Justine appear to have found a workaround. She's adventurous and her name is Mara.
[[/folder]]

[[folder:Live Action TV]]
* The early episodes of ''{{Smallville}}'' subverted this trope, as Clark Kent got weak and klutzy whenever he approached Lana Lang not because of his crush (which [[LoveMakesYouDumb only affects his judgement]]), but because of her kryptonite necklace.
* For an episode of ''{{Scrubs}}'', J.D. had to deal with an element of this, when he couldn't get some of the ugly scenes from work out of his head and looking at any part of his would-be girlfriend ended up making him think of some scene involving that part of the body (throat cancer when he looked at her neck, etc). He was able to move past it with some "help" from Drs. Cox and Turk.
** Okay, [[FreudWasRight that just]] [[HoYay sounds wrong]].
** And really, Elliot was much more ''helpful''...
** Speaking of Elliot, she also has been known to throw up when she's nervous- one notable occasion occurring in front of her ex-boyfriend Sean, when his incredibly hot new girlfriend shows up out of the blue.
* An early episode of ''NorthernExposure'' had Chris struck dumb by meeting a beautiful woman. This prompted many of the citizens of the town to reflect that they felt sick when they met their partner; the one man that felt happy was dumped by his girlfriend 3 weeks later.
* Played with in ''NoahsArc''. At the start of one episode Ricky looks unusually pale, and Noah askes if hes sick. Ricky says he thinks hes "falling in love", implied to be thinking about Junito, and then passes out. He wakes up later in a hospital (come to find out, it was a Staph infection).
[[/folder]]

[[folder:Music]]
* The Shins have a song called ''Know Your Onion'' which mentions this
--> "I left all my friends at the morning bus stop
--> Shaking their heads
--> 'What kind of life you dream of?
--> You're allergic to love!'"
* The song ''Tongue Tied'' by Danny John-Jules (memorably featured in ''Series/RedDwarf'') is about the singer trying to confess his love to a woman, but suffering a variety of symptoms from weak knees to ''vomiting'' every time he tries to talk to her.
[[/folder]]

[[folder:Theatre]]
Representative lyrics from "Love I Hear," from "A Funny Thing Happened on the Way to the Forum":
--> I'm dazed I'm pale, I'm sick, I'm sore,
--> I've never felt so well before!
[[/folder]]

[[folder:Video Games]]
* Not only is [[Characters/DisgaeaHourOfDarkness Laharl]] from ''VideoGame/DisgaeaHourOfDarkness'' allergic (as in gets ''literally'' hurt by: his [[GameplayAndStoryIntegration stats get cut]]) women with sexy bodies, he is also allergic to optimistic sayings, especially "Eternal love".
** And don't forget optimistic sayings said ''by'' women with sexy bodies. "A ray of hope" isn't overly much for Laharl when said this way.
** Laharl isn't as straight an example as he'd want you to think. He clearly loved his mother at the very least and has quite a bit of running UST with Flonne.
* Apricot from ''Anime/GalaxyAngelRune'' and ''[[VideoGame/GalaxyAngel Galaxy Angel II]]'' is a female example, whose [[DoesNotLikeMen androphobia]] is so strong that it manifests into SuperStrength and she [[MegatonPunch hurls any man that touches her several meters into the air]] -- the exception being the game's lead, Kazuya. Oddly enough this affectation is also in the television series, despite the [[ImprobablyFemaleCast lack of fodder]].
* ''VideoGame/KingsQuestIVThePerilsOfRosella'' takes this to the logical extreme: the villain Lolotte is so evil that when Rosella shoots her with one of Cupid's arrows, the love is so poisonous to her that she dies.
** Not that being ''shot with an arrow'' is healthy in any case...
** It didn't seem to hurt the unicorn at all. (Either that or Rosella handing the unicorn over to Lolotte hurt it much, much worse...)
* In ''VideoGame/SuperRobotWars'', this is the aftermath of Tytti Noorbuck after witnessing [[spoiler:her would-be lover, Ricardo Silvera, protects her by TakingTheBullet directed to her from her ArchNemesis]]. After that, she was scared to form any relationship with another man.
* A rare example that is as much dramatic as comedic: in ''VideoGame/TalesOfTheAbyss'', party member Guy (pictured above as he appears in TheAnimeOfTheGame) suffers from severe gynophobia, specifically being touched by women. Its origins, rather than funny, prove to be quite horrific.
** [[spoiler: A whole room full of women, including his beloved elder sister, died to protect him right before his eyes, and he got stuck under all the dead bodies for ''days'' until someone came to rescue him. He blotted this out of his memory, and could only subconsciously remember that "Girls=scary," thus leading to his gynophobia.]]
* ''{{Persona 3}}'' has Chihiro Fushimi, the student council treasurer, who starts off as being nervous about talking to men. As you progress her Social Link more, she starts becoming more confident.
* Lord Dearche of the ''VideoGame/MagicalGirlLyricalNanohaAsPortable: The Gears of Destiny'', as hilariously shown in [[PlayableEpilogue Sequence X]], has an adverse reaction to the idea that anyone could like her.
--> '''Yuri:''' Thank you... Dearche, our kind King. I love you.\\
'''Dearche:''' E-Eeei! Will you stop that?! A chill is running through my skin! You! Have you forgotten that I was born a King of Darkness?! \\
'''Yuri:''' You're my important Dearche and everyone's King. I haven't forgotten and I'll keep on saying I love you no matter how many times.\\
'''Dearche:''' [=U-uwaaaAAA=]~!!! Shut up already!! Shut uuup!!! No, it doesn't matter if you don't! With my power as the King who rules over Darkness, I'll shut that loose mouth of yours to never say those again!
* Cultist in the TowerDefense Game ''Leave [[CthulhuMythos Cthulhu]] Alone!'' states that "hugs make me break out in [[{{Squick}} huge]] [[BodyHorror cysts]]."
[[/folder]]

[[folder:Webcomics]]
* In ''Webcomic/{{Sinfest}}'',
** [[http://www.sinfest.net/archive_page.php?comicID=2054 some language]] [[http://www.sinfest.net/archive_page.php?comicID=2055 has some harmful effects]].
** "[[http://www.sinfest.net/archive_page.php?comicID=2245 Yech! Ick!]]" This includes angel-glitter and (of course) "[[http://www.sinfest.net/archive_page.php?comicID=2613 father-son thing]]".
** Lil' E -- [[http://www.sinfest.net/archive_page.php?comicID=2036 Or says so]]. Still fails at not being cute in process. [[http://www.sinfest.net/archive_page.php?comicID=2575 Angel-glitter too]].
* Tavros, of ''{{Webcomic/Homestuck}}'', is a ShrinkingViolet by nature. It only gets worse when he's propositioned by Gamzee (and later Dave, who does so as a joke- though Tavros doesn't realize that). This is likely because Vriska's abusive stalking turned him off towards romance as a whole.
** Jack Noir, one of the [[BigBad Big Bads]], is disgusted by feelings of love and affection. He [[spoiler:hates that he is unable to kill Jade after being prototyped with her dog/guardian Becquerel, and promptly flees when he falls for a very angry Peregrine Mendicant]].
* ''Webcomic/FurryExperience'': Whenever Hunter, a husky, attempts to asks Cat out, she [[RunningGag runs off in a panic]].
[[/folder]]

[[folder:Web Original]]
* Charlie, the main character in [[http://www.fictionpress.com/s/2535577/1/Charlie_Daniels_Teenaged_Schmoe this story]] is a fairly unique case of this trope. Whenever people start being mushy or making out near him (especially making out), he usually ends up with heartburn. He often uses this for comic effect (i.e. to weird people out)
[[/folder]]

[[folder:Western Animation]]
* In early seasons of ''WesternAnimation/SouthPark'', Stan vomited uncontrollably when his love interest Wendy Testaburger so much as talked to him.
** This seems to have started all over again at the end of the episode ''The List''. Though in ''Super Fun Time'', he holds her hand through most of the episode with no ill effects. Then in ''Elementary School Musical'', she kissed him without Stan puking on her.
* On ''WesternAnimation/{{Daria}},'' one episode has the protagonist get a mysterious rash on her skin which turns out to be stress-related. She first gets it at the Zon when she and Jane are hanging out with her crush, Trent, and at the very end of the episode gets a suddenly relapse when Trent shows up on her front door.
* In one ep of ''WesternAnimation/TheFairlyOddParents'', Trixie falls for Timmy after he loses his emotions. When he doesn't respond, she decides to date Chester to spite him, much to Chester's dismay; he actually breaks out in hives.
** He also finds A.J.'s crush on "Timantha" disturbing. (Granted, [[{{Squick}} it]] ''[[{{Squick}} was,]]'' [[{{Squick}} but still.]])
** Also, Mark Chang can't handle human forms of showing love. In fact, it causes his alien tech to short out. Unfortunately the default human form on his transformation belt is quite pleasing to the ladies, making this a rather large issue.
* Rico, of ''{{The Penguins of Madagascar}}'', has 'mushy love sickness'. Meaning any mushy display of affection (or anything mushy really) will cause him to become sick and vomit. This doesn't get in the way of his [[{{cargo ship}} relationship with his doll]] however.
** In the one episode it comes up, it actually saves his life, as it helps him get rid of a TimeBomb he had swallowed and was unable to barf out again.
