That guy that swoops in and takes ur girl at that exact moment you weren’t looking. He can be a close friend or someone you know through other people, but either way, you will hate him because you liked him before he stole yo girl.
Noun. From "Bottoms Up" by Trey Songz (feat. Nicki Minaj). A cocky, sex-obsessed, douchebag male who will try to get a girl to dump her boyfriend so he can have sex with her.
Club patron: "Hide yo females! Mr. Steal Yo Girl just walked in, yo!"
