A term created by some to allow them to go beyound the realms of decent behaviour, and indulge in racist and sexist messages, all in the name of b-anter.
"Man, thats racist you idiot"
"Chill, its only b-anter"
B.O.B. stands for Blacked Out Bitch, a person (can be male/female) that is blacked out (i.e. cannot remember what happened to them due to drinking too much alcohol)
Boy 1: Why can't I remember anything last night?
Boy 2: Because you were a B.O.B! You drank way too much 4 loko.
