bro 

Guys who wear popped collars, baseball caps, american eagle and aeropostale. They like to play sports such as hockey basket ball and golf. On rare occasions they have a tattoo. Usually a bro can be seen on weekends shot gunning beer or listening to Kanye West. In most cases bro's are closet cooler drinkers. They are always found with their other bro friends and usually with blonde heavily made up girls.

bro 

Usually a cocky douche bag who wears polo shirts (especially popped-collar), and likes to walk around with a starbucks iced cappachino while wearing a Northface jacket. The person is a preppy bitch who thinks they're hot shit because they're rich spoiled little assbags. Commonly, bros are whipped bitches who buy girls shit in the hopes that this will get them some, but the girls are only using him for his free shit.

Jake: Look at that kid over there. What a bro. Lets kick his ass.
Matt: Ya, that kids a douchebag.
