G.N.B is an acronym for the phrase "Get No Bitches". Usually if youre part of a crew or a group of people that do not get any pussy whatsoever, you can add this as a label to your group. You can walk around with your friends who get no type of pussy just like you and yell G.N.B like it was some type of gang saying. It sounds cool in acronym form.
