A word used by professional wrestlers to describe underage groupie girls that hang outside the door that leads to the dressing room or locker room. When a pro wrestler comes out from the dressing room, they scream at a very high pitch. Ring rats will try to get the attention of a pro wrestler, seeing if they can get a date.
