Being a "bro," contrary to popular belief, is not a bad thing. A real "bro" is in general, just a cool mother fucker to know. Bros know about sports in great detail and pretty much are the center of attention in everything he/she does. Only extremely lucky women/girls can be "bros." Whether it's watching a game, or engaging in general "bro-ness," bros are always doing what you wish you were doing. Being a bro comes with responsibilies: being the head bro constitutes making decisons that directly effect other bros. If you're not up to it, don't take on that task, you'll thank yourself for it later. Bros engage in bro-pong, which is a variation of beer-pong. Bro-pong isn't that much different, it's actually the same, just played with real bros. Frat backgrounds are preferred, but no necessary. Basically, being a bro is the preferred status of men 18-30. If you're in your 40's and still consider yourself a bro, you are too old. Put down the beer bong, and go pick your kids up from soccer practice.
"Bro, today I watched the Tigers beat the Yankees."
"Really? Bro, they suck!"
"I am glad to have a bro like you (girl/guy)."
