Chick who is basically like one of the dudes, similar to tomboy status, but less manly. One who hangs out and does dude-ly things, but knows her limits. Not to be confused with Bro-ho, a bro-chick is a girl who will sit back, drink beer, play videogames and football with you, and still spend 5 fucking hours doing her hair and makeup.
Bro 1: "That chick is so cool to hang around with. It's like she likes all the same things me and my bros do"
Bro 2: "You don't think--"
Bro 1: "Yeah. It's official. That chick is totally my bro. She's a bro-chick."
