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 anything to get her hands on the women she desires.
- Downplayed:
- Alice is only marginally less pleasant than the average people.
- Alice Facebook-stalks Stephanie and keeps a 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.
- Alice is a Blood Knight, Heroic Comedic Sociopath and/or Token Evil Teammate nontheless on the heroes' side.
- Alice is a Laughably Evil Harmless Villain.
- Alice sexually harasses Stephanie and hits on her aggressively, but backs off after meeting her boyfriend/girlfriend.
- Justified:
- Alice's girlfriend was assaulted, resulting in her death, and Alice is now on a Roaring Rampage of Revenge, which has been going on for so long that's it's had a considerable detrimental effect on her sanity.
- Alice is a Yandere who happens to be a lesbian.
- Being a lesbian doesn't make anyone less susceptible to The Dark Side.
- Alice has a Dark and Troubled Past and Stephanie was the only one who always treated her kindly.
- Inverted:
- Alice is the Only Sane Man in a cast of psychotic straight people.
- Alice is a lesbian and about the nicest girl you could ever hope to meet.
- The villains are a straight guy who thinks Girl on Girl Is Hot and a rabid Yuri Fan that creep out Alice with their unwelcome propositions.
- Alice is persecuted by deranged anti-gay bigots.
- Gender-Inverted: Depraved Homosexual
- Subverted:
- Alice acts insane, but that's only because her girlfriend Stephanie is a Nightmare Fetishist.
- Alice is insane... and so is her boyfriend.
- Alice is a lesbian, but she's actually a Chessmaster of the highest calibre. She's just invoking Obfuscating Insanity to ensure that nobody picks up on her true goals.
- When Stephanie turns her down because she's straight, Alice starts to shake in anger but takes a deep breathe and gracefully accepts it.
- Alice says that she’s straight and loves Stephanie platonically.
- Despite her behaviour, Alice doesn't actually harbour any romantic feelings towards Stephanie, she actually has feelings for Bob.
- Double Subverted:
- Alice is insane, but she is not a lesbian. Until she meet her Closet Key, anyway.
- Alice ends up Kicking The Morality Pet until she runs away/dies and goes back to just being a psychotic lesbian.
- Alice's insane persona ultimately starts taking over and she snaps for real.
- But when rejection after rejection after rejection starts to get to her, Alice becomes less "gracefully accepting" and more Yandere.
- Alice is lying.
- Parodied:
- The lesbian villain Alice enters loudly the scene, wearing a tampon costume and singing her Villain Song about munching carpets.
- Lesbians in the show are all Straw Feminists.
- Alice comes out of the closet, and immediately turns into a harmless Cloud Cuckoo Lander, with 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 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.
- Alice is evil and/or insane, and she prefers women, but those aren't connected. She doesn't stalk or harass women who aren't interested in her, and her relationships are healthy and humanizing and/or with women just as bloodthirsty as she is.
- 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.
- Lesbian Vampire
- 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 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 daughter.
- 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.
- 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: Lesbians like Alice go insane because everyone assumes they will, and because of homophobia.
- Reconstructed: Many lesbians overcome the prejudice, and are especially motivated to stop the psychos.
- Played For Laughs: A Romantic Comedy series which casts are all Psycho Lesbians.
- Played For Drama: Alice has fallen in love with Stephanie, but Stephanie's straight. Stephanie is afraid of telling Alice she doesn't swing that way for fear of what her reaction might be.
- Played For Horror: Continuing the "played for drama" example, we find out what Alice's reaction would be, and boy it ain't pretty.
- Implied:
Back to Psycho Lesbian, my darling. You do know that no male will ever love you the way I do right?
