Girls in their pre-teen years (11-12) who dresses like and/or has a major potential to be a slut. Worst case scenario, they may already be on their way to becoming one.
Mark: Did you see what my sister looked like today?
John: No, why?
Mark: She was wearing a mountain of make-up and this low-cut top when she hardly has boobs. She's such a pre-slut.

Jess: How was the party last weekend?
Mary: Good, except there was this random 12-year old girl hooking up with like 8th grader boys.
Jess: Oh my God, what a pre-slut.
