a person (usually female) that keeps sending you friend requests even though they don't know you and you don't know them. Usually done in order to watch your comments in hopes that you'll say something about someone they know. Basically another word for a "snitch."
You: "Hey, you know Sally James? She keeps sending me Facebook friend requests."
Friend: "Nope, she is a Facebook Creeper. Whatever you do...don't add that Facebook snitch!"
Friend: "Nope, she is a Facebook Creeper. Whatever you do...don't add that Facebook snitch!"

Someone who finds your facebook account logged-in when you're not around and proceeds to change your status and/or profile information.
I think Mike may have been visited by a facebook fairy. His status says he can't come over to watch the game tonight because he's decided to adopt 20 cats and is knitting each of them a little pink sweater to "keep the kitty warm and pretty." LMAO!
