BG. It's emblematic of someone who is a pure boss and fucks bitches. It is based upon a Florida Highschooler some years back who graduated valedictorian of his high school, played 3 sports, and had the hottest piece for a gf. It has since gained widespread popularity at many Florida State Schools.
That guy is so fucking BG - he fucked the hottest girl in KD and wrecked the curve in his graduate student class.
"'That guy is Boss.' 'Nah Motherfucker - he's straight BG.'"
you know how you play "slug bug what color" when your extremely bored or if you just want to hit your friend, BG is a similar game in which you most commonly use in church to identify a BG or Bald Guy them following with a punch to the shoulder toward his friend.
