1.
To use the pro bro styles, look up bro and put pro with it. What do you get?

PRO BRO.
He is a Pro Bro. Pro Bro can be a good or a bad thing, usually bad. Again, don't be stupid and go look up bro.

2.
A professional bro. Someone who is too dope for words.It takes many years and experience to become a "Pro-Bro". A pro-bro can treat the ladies right, is always in style, can beast it up at any sport, is tight with every clique/everybody, and still manages to get sweet grades and turns out successful in life no matter what. A guy that does what he wants, and not what others say.
