F.R.B's stands for Free Range Boobies. Just like free range chickens the girls allow their boobs to be roaming freely under loose shirts.
Hay dude! Look at the major nipple reaction (MNR) on those F.R.B's. Must be the summer breeze.

RB Stall Highschool

RB Stall High school is one of, if not the worst high in south carolina. The Hallways always smell like fish because girls dont know how to wash their coochies. Most of the staff and teachers are rude as fuck. cases of teachers fucking students come out sometimes, there isnt a day where a fight doesn't happen, students literally smoke on the busses, and students literally FUCK in the bathrooms... many of the students are either homophobic or racist, hell most of them are both. be careful if you attend here.
boy: have you heard of RB Stall Highschool?
Girl: yes a friend of mine told me about it, its so ghetto..
