To be a postwhore, post frequently and mindlessly on postwhoring dot net (also known as PW). Postwhores think they're hilarious and perv on everything. If that sounds like you, then you're probably a postwhore.
"Why are you being such a creepylurker? Are you fapping? You are, aren't you. Well jeez dude, a true postwhore would make a thread about it."
