peacock
A girl that looks awesome from the back, but busted from the front. Not to be confused with a butter or butterface (but-her-face) who has a hot body and a busted face. A peacock will have a jlo booty and tiny waist, but lopsided titties and a face that resembles what you saw in the toilet after you last all night drinking binge bacon dog cart adventure.
