Found primarily in the northeast and deep south, a bro is typically a white male from a wealthy background who enjoys excessive drinking and partying, sports
(especially lacrosse), and music (usually underground rap (wiz khalifa, oncue), alternative (kings of leon, DMB), and techno) Bro's dress differently depending upon the region they live in, but the main elements include polo ralph lauren, sperry's, and designer sunglasses (costa del mars, ray bans). Bro's use the college they attend or attended as status symbols and most Bro's post-college can be found in the financial business. Bro's are considered to be extremely success oriented and their aggressiveness in life tends to anger several other societal groups (see hipsters).
Bros can be found in the majority of the male characters in Wedding Crashers, anybody who plays lacrosse, or Stifler from American Pie.
