i figured out a way to reject jerky guys:
him: so, when are we going out, baby? *tongue action that i can only imagine is supposed to be a preview of things to come*
me: oh, so you just assume i'm single? that no one would have me? is that it?!
him: um, no, not at all, i just meant... you know what, forget you, bitch. you're probably a lesbian anyway.
