Jake: Naw, she's a wereslut.

A person, usually a girl, who becomes indistinguishly slutty at a certain time of day, or on the weekend. They are most easily spotted in their usual habitat, anywhere that alcohol is being served in abundance.
Amber: "Look at that girl over there, she looked so nice when she came into the club, what happened??"
Kate: "She's a wereslut, normal during the day, whore at the club."
