Creeper

1. This is the only valid use of the word: A guy who looks at kiddie porn, molests children, rapes women, etc. 2. Otherwise it is a rather juvenile word to denote someone different. For example some random guy in the back of a photo, as if he intentionally was there to be creepy. Generally someone, almost always a male, who is different. They may have Asperger's or some other such condition, and so not able to socialize very well, they come off weird, even too strong sometimes, especially towards women. Vain, conceited women call them creepers because they are rather foolish and insensitive to what others suffer. Just like they might not understand everyone is not as well of as them money wise, they forget that not everyone is socially skilled as they are. It also denotes a guy who is perhaps artistic, scientific, etc, who does not act like a total ass. His male peers may call him this. In short, it is a overused term that should only be used for perverts, but has been applied to any guy who is a bit different.
