Acronym for 'Best Friend's Brother'. Just like in Victorious Justice's song "Best Friend's Brother" where she constantly says "My Best Friend's Brother is the one for me." and then says "BFB!! BFB!!"
"My Best Friend's brother is the one for me! YEAHYEAHYEAH! A Punk rock drummer and he's 6 foot 3! ... BFB! BFB! My best friend's brother, my best friend's brother!"-Victoria Justice
