A bro (noun) is a friend until death and beyond that. He will always help a fellow bro score with a chick, by whatever means necessary. Being chosen as a bro is a bigger honor that that dumb medal Mr Myagi had in The Karate Kid.
Bro 1:Hey Bro, I need that chick to believe I’m famous to score, Bro
the word "bro" started as a shortened version of the word "brother", but quickly evolved to a word that you could call not only guys that aren't your brother, but instead, anyone at all.
