I see all of those questions asking what thing will be the next hot niche... To answer those questions I have written my Amazing Fetish Generator that has all the answers, it suggests everything from simple fetishes like:
"Dumb blondes doing math in public"
to more complex ones, like:
"Fat police officers violating virgins to the sound of farting midgets"
For a quick laugh (or at least a smirk), check it out at

PS. If it produces a fetish that offends you - go fuck yourself!
PS2. Yeah, I was bored... How did you guess?
