A facebook, myspace, or aim profile of a pedophile, that uses pictures of the same preteen girl or boy to lure other children in. Usually a male in his late 30s, fat, many chins, glasses, and enjoys world of warcraft.
Jack: Did you see that hot girl's profile pictures on facebook Sam: Dude, stay away, I think that it's a prodephile
Jack: I think you could be right
Sam: I have to be right, on "her" interests it says dragons
Jack: Thanks man, that was close, i almost gave him my address
A person you hate intensely not because they deserve such hatred but because they serve as a focus for your general hatred. A healthy way to dispense with excess animosity.
Jake's not really that big an asshole. He just serves as my hate sink.
