I have this general theory about creepy. Guys can be creepy but women can't be creepy, at least in the sense of the word as a woman uses it to describe a man. Women can get away with all sorts of messed up crap and get away with it. A woman can stalk her ex-boyfriend and it's socially acceptable. A guy could do something as good intentioned as bring a female acquaintance a bouquet of roses and be labeled so creepy he's one step away from getting the pepper spray.
Of course on the flip side, I told this theory to a lady friend of mine and she said guys can't be called sluts, because that behaviour in a man is socially acceptable.
