someone who is a slut but doesn't sleep around with guys. Just makes out with them. Maybe does a little bit of third base (i.e. blowing)
Friend 1: did you see that girl last night? she was totally making out with that guy!
Friend 2: Really? but i hear she is a virgin? and look now she's making out with that new guy from French class!
Friend 1: She's such a minor slut.
