This is a phrase that came to me when I was talking to my 13 year old son. It's intended meaning is to tell someone they are annoying you or as a response to a over the top, funny or ridiculous conversation but said in a very light, loving and joking manner.
For example, when someone is talking too much or saying something outlandish, ridiculous, funny or annoying. "You're creepin or You're creepin me". It's all said in fun, like "get out of here or you're crazy"!
