The BC's are the most badass gang found in a suburb of Chicago known as smoke park reefer forest. BC's should not be messed with because they are known to fuck shit up. No one except for members know the exact definition of BC, but it has been speculated to have many different meanings. In their free time, BC's get crunk, drop beats, and get money.
Boy#1-"oh shit.. is that a BC over there?"
Boy#2-"fuck, we better turn and run"
