A male, often in (but not restricted to) his late teens to mid twenties, whose most raw state would be what many would consider a "regular dude." On this crude foundation, bros layer an exuberant confidence because of good looks, wit, respect from other bros, success in sports (carnal pursuit being a sport), but more often than not a combination of all of these. This confidence when combined with all of the features that make a bro not "weird" or a "fag", sometimes leads to a prejudice against the lesser "weird" "fags", often vocalized in a bro's boisterous manner.

Most comfortable in social settings with limitless amounts of alcohol (hence the common association to fraternities), and an impressive coherency despite the amount of alcohol consumed. This, in combination with said confidence, has lead bros to exploit glaring insecurities in women, often by putting down and manipulating said women, which is more proof of female stupidity than any given bros demeanor.

A bro's wardrobe is perhaps the most interesting aspect of the creature, as it the most versatile of any other genre of person. There is a notable balance between every category of clothing, save emos, guidos and said "fags”. For example a flat brim(ghetto), throwback John Stockton jersey, nice shorts (preppy), and turf shoes(lax), is a staple broutfit. Not all bros necessarily have this outfit, aspects of even skater, surfer, or even casual luxury apparel withstanding, but girls will stare regardless.
You should have seen Danny's dad at the wedding; he was pounding straight Beam and hitting on all the waitresses while giving his two high school nephews beers. So we iced him and he crushed the bottle, spiked it, flipped the table and blamed the whole thing on the mexican janitor. What a Bro.

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.

A young man, typically white and middle-class, fettered by his narrow and insecure view of masculinity. This manifests in his conforming lifestyle to other bros, disinterest in intellectual matters (or anything beyond sex, sports, and parties), and sometimes aggressive and intolerant attitudes.

a status higher than best friend. A bro always has his bro's back. You can easily spot bro by finding a small group of males doing something stupid. Contrary to popular belief, a girl can also be a bro. They mainly live by a set of rules (or guidelines) commonly called the BRO CODE. Brah and Bruh are different pronunciations typically used by douches to refer to basically any other male and should not be used unless you want to sound ridiculously douchey. The bond between 2 bros is everlasting and very rarely breaks apart. Many times, the bros will assist each other when hitting on chicks and a good bro will always jump on the "grenade" when his bro is hitting on a chick with an ugly friend in order to attempt to ensure that his friend will receive the best outcome possible. Unfortunately many young males misuse this sacred title reducing it to nothing but an obnoxious phrase a guy calls everyone in his frat.
Douche 1: sup brah?
Douche 2: sup bruh?
guy 1: dude they are such big douches
guy 2: yeah i know right? Hey bro, i met this chick i really like. You think you can help me get her?
guy 1: I got your back bro.
