Communities - The making of

I've mentioned to several people that I'm going to be making three new communities soon. One of them actually requires input from people.

The premise of this one: a claims community, with a list of themes that are "fic clichés". Obviously my list will be limited by the fics I've come across, so I'd appreciate it if loads of people would help me.

Criteria:
-Mustn't be fandom specific, unless it's specific to many fandoms -- e.g. "using potion for lube", which is relevant to Final Fantasy games, Pokémon, etc, etc. If I get many like that, I'll make a separate themes list for them.
-Must be some kind of story cliché -- it doesn't have to be fic.

...And that's it. I have a few myself, and it depends how many contributions I get on how many themes lists I have. Don't worry about submitting something I already have, I'll be sorting things anyway.

Examples:
-Hurt/comfort fic
-Hate turns into love
-Highschool AU
-Vampires
-"I didn't realise I was [insert sexuality here] until you kissed me"
