A person who not nesessarily stalks other people, but gives you the creeps and might do awkward things. This person does not have to be a stranger either. You can know them well, but is not someone you want to associate with.
Girl One: Wow, Leon is such a creeper. He's sitting all by himself in the loner seat at the movies.
Girl Two: Yeah, what kind of person sees Reno 911 by themselves, anyway? What a creeper.
A person who is desperate for any attention, but fails to get it. Creepers are always in the pursuit of CAF though they deny that they are. Creepers often possess humongous eyes that make any conversation with one of them extremely awkward. Creepers use thier eyes to creep off and stare at CAFs for hours on end.
Girl: I swear he's been staring at me for over an hour.
Other Girl: Don't you know?
Girl: Know what?
Other Girl: He's a creeper!
Girl: Ahhhhh!
