(n.) One who is afraid to have an opinion, and rather, simply points out the flaws of what everyone else is saying. Dislikeable to all. The exceptions are those fence-sitters that really don't give a shit and make fun of everything, who are liked by all.

A negative term for someone who is bisexual.
I thought she liked girls, or is she a fence-sitter?
