1.
A girl who fucks brothers especially her friends brothers. Like a motherfucker but instead a brotherfucker. The girl will usually still be in high school or senior school and her friends brother is usually a few years into their university course.
Man. I can't believe she slept with your brother last night. What a brotherfucker.
