All the girls on facebook with slutty profile pictures. Or all the girls on facebook that are "friends" with your boyfriend.
Girl to best friend, "Did you see that facesluts' profile picture? Wearing her Christmas bikini in the snow! Tyra would be so proud!"
Girl to boyfriend, "Oh, honey, look! All the facesluts wished you a happy birthday!"
