A state of being in which a guy's face just seems to say that he is (going to be) a rapist. Every facet of their face and general demeanor screams, "CREEPY" and makes you want to get to a safe location with lots of lighting and people.

An excellent sign that you should steer clear of this one.

Kate: "Yeah, I guess I'd rather stay home than go out with a future rapist."
