"Use obscure euphemisms and clichés"
^ Right from "Whose Line Is It Anyway"

1) Serebii Forum Rules apply.
2) You have to talk only in expressions, phrases, euphemisms, etc., adding "if you know what I mean" onto the end of each one.
3) They don't always have to make sense, sometimes they're funnier if they don't.
4) Keep it appropriate, and have fun.

Here's an example:
"Yeah, I went shopping for groceries today, if you know what I mean."

Have at it!
