2.
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.
