A Bro is the common douche bag frat guy. He's at all the parties wearing Abercrombie & Fitch one night with extremely gelled hair, and the next night he's decked out in Famous Stars and Straps and a gangsta hat that he picked up at Pac Sun. And oh boy, he thinks he looks good. They are commonly seen walking into parties calling each other "bro" and "brosef." They actually like that, and they especially love getting bro-fives. The terrible tribal tattoo around his arm or across his back will be seen at some point during the night, probably when he gets "too hot" but really wants everyone to see his "nice abs."
