A young girl between the ages of 8-14 wearing shit like pushup bras, daisy dukes, thigh highs, shirts that say "slut" or "whore" and trying to look like they're a 30 yr old crackhead. Usually can be found txting other prostitots at the mall and/or myspacing... the only thing they have to look forward to is a life full of cum swapping, nut stained panties and whoring themselves... all before there's even grass on the field.
Generally used as an insult towards woman... or men. Same thing as callin someone a bitch or whore. It's the act of after a man has ejaculated into one woman's mouth, she then passes it to a second woman. And continues. It's now become a derogitory term me and my friends use to talk shit about someone.
Guy1: I talked to heather and...
Guy2: and what?
Guy1: nothin due. She was just being a cumswapper.
