Ted - "Yea bro, its A Real Butt Fucker, we should totally play it at our kegger this friday. We're gonna get so much pussy!"
a chick that is so depraved that the only way she can get off is by being aggravatingly fucked in her ass while she violently slaps her own clit or pussy, usually ends up to be a porn star.
