a really chill dude who plays lax, drinks natty, gets dome, chills with his bros. he gets his bitch to make him sandwhiches and give him dome while he plays cod.
I know that some of those socal dudes call themselves bro's like they are in some sort of gang or something but up here in the Bay, bro means someone that you feel close too, ie. your friends would be called your bros, bro can also be used instead of dude.
To the Socal "bros" Im from pittsburg and antioch and alot of us use bro, but we dont care for kotton mouth kings, dirt bikes, lifted trucks, or other deuchey socal bull shit, all those fancy clothes make you guys look prissy Take that shit back to huntington beach you dick riding faggots.
