'''Basic Trope''': A lesbian who is insane, especially due to unrequited love for another female character.
* '''Straight''': Alice, a lesbian character, is mad about Stephanie. Literally.
* '''Exaggerated''':
** Alice is completely out-of-control and will do [[MurderTheHypotenuse anything]] to get her hands on the women she desires.
** Every single lesbian character in the universe is confined to a mental institution.
* '''Downplayed''':
** Alice is only marginally less pleasant than the average people.
** Alice Facebook-stalks Stephanie and keeps a {{hair|Decorations}}pin that she saw fall out of Stephanie's hair. But really, she's mostly harmless, if a bit annoying.
** Alice is a lesbian and a {{Cloudcuckoolander}}, but she doesn't try to hurt anyone.
* '''Justified''':
** Alice's girlfriend was assaulted, [[BuryYourGays resulting in her death]], and Alice is now on a RoaringRampageOfRevenge, which has been going on for so long that's it's [[HeWhoFightsMonsters had a considerable detrimental effect on her sanity]].
** Alice has been experiencing a series of relationship breakdown.
** Alice is a {{Yandere}} who happens to be a lesbian.
** Being a lesbian doesn't make anyone less susceptible to TheDarkSide.
** Lesbian women represent a large group (even if only 1% of women in the world were lesbians, it would still mean 35 million lesbians). Women suffering from dangerous psychosis are also a large group (if 1% of women were dangerously psychotic, it would account for 35 millions of them). Statistically, some degree of overlap between two sufficiently large groups which are not mutually exclusive is virtually guaranteed (assuming they are independent variables, that still leaves an expected number of lesbians who are crazy at 35,000). So statistics dictate there would be at least a few psychotic lesbians running around.
* '''Inverted''':
** Alice is the OnlySaneMan in a cast of psychotic straight people.
** The villains are a straight guy who thinks GirlOnGirlIsHot and a rabid YuriFan that creep out Alice with their unwelcome propositions.
* '''GenderInverted''': DepravedHomosexual
* '''Subverted''':
** Alice acts insane, but that's only because her girlfriend Stephanie is a NightmareFetishist.
** Alice is insane... and so is her boyfriend.
** Alice is a lesbian, but she's actually a [[TheChessmaster Chessmaster]] or MagnificentBitch of the highest calibre. She's just invoking ObfuscatingInsanity to ensure that nobody picks up on her true goals.
* '''Double Subverted''':
** Alice is insane, but she is not a lesbian. Until she meet her ClosetKey, anyway.
** Alice ends up [[KickTheMoralityPet Kicking The Morality Pet]] until she runs away/dies and goes back to just being a psychotic lesbian.
** [[BecomingTheMask Alice's insane persona ultimately starts taking over and she snaps for real]].
* '''Parodied''':
** The lesbian villain Alice [[LargeHam enters loudly the scene]], wearing a tampon costume and singing her VillainSong about munching carpets.
** Lesbians in the show are all {{Straw Feminist}}s.
** Alice comes out of the closet, and immediately turns into a harmless CloudCuckooLander, with [[TheDreaded everybody terrified of her.]]
** Alice is revealed to be a lesbian, and nobody dares look at her, for fear they'll be hurt.
* '''Zig Zagged''': Alice is actually trying to ''escape'' from Emperor Evulz and is constructing a plan with Stephanie, but before that can happen, she breaks from the stress and goes ''truly'' insane, then Stephanie reveals that ''she'' has been working for [[MeleeATrois Master of Destruction]] all along..
* '''Averted''':
** Lesbians are just as sane or insane as the rest of the cast.
** There are no gay characters in the cast.
* '''Enforced''':
** "''True'' lesbians are very efficient as scary opponents since women fear being raped by them and men just can't seduce them."
** Alice is in an anime/videogame/name-your-medium-here that covers a lot of fetishes.
* '''Lampshaded''': "My dear Stephanie, you don't seem to understand. I want ''you'' and no is not an answer. Simple as that."
* '''Invoked''': Bob intentionally drives Alice insane because he's [[MindScrew working for a fourth evil mastermind...]]
* '''Exploited''': Emperor Evulz hires an entire battalion of lesbians, promising that the most bloodthirsty and most psychotic one will be able to molest his dauther.
* '''Defied''':
** "I'm not insane. I just happen not to want to suck your penis or anybody else's for that matter. Your genitals are not a recognized measure of female sanity, are they?"
** Alice eventually calms down and realizes that she won't get ''anyone'' to like her through her behaviour and resolves to remain a lesbian but to be more reasonable about it. It's an ongoing process.
** Alice is a lesbian who suffers from schizophrenia, but she sees a psychiatrist and takes her medication properly, allowing her to live a normal life.
* '''Discussed''': "Gee, I hope Alice doesn't go insane. She took Stephanie's refusal ''hard''."
* '''Conversed''': "There's hardly any positive non-bisexual lesbian on screen these days..."
* '''Deconstructed''': Her insanity leads her to IfICantHaveYou and she just won't accept any woman she has set her views on to say no to her.
* '''Played For Laughs''':
** A RomanticComedy series which casts are all {{Psycho Lesbian}}s.
** Alice is AxCrazy, a Lesbian... and very aware of the UnfortunateImplications of such. At least once, Stephanie manages to escape her by pointing this out and sending her [[CharacterFilibuster into a full-on rant about how "Being gay doesn't make me crazy; being crazy makes me crazy!"]]
* '''Played For Drama''': Alice has fallen in love with Stephanie, but [[IncompatibleOrientation Stephanie's straight]]. Stephanie is afraid of telling Alice she doesn't swing that way for fear of [[{{Yandere}} what her reaction]] [[IfICantHaveYou might be]].
