A bro is commonly a white male in college, anywhere from the age of 18-24. Bros consist of their fraternity, and are normally found poundin' natty ice with their bros, laxin' (lacrosse) or partying. Bros wear their lax pinnys, or no shirt at all. Bros are also found poundin' their slampieces all the time, while either driving or playing CoD.
