look up any word, like the eiffel tower:
Typically a female who is a "bro" but can't really be a "bro" without being male. Brosita's are equal to Bro's and are also as Badass as them if not more. They do not drive lifted trucks as more or less Classic trucks like 1966 Chevy Pick-ups. They live their life the way they want and don't take shit from anyone. Pronounced "bro-seet-ah."
Dude, my girlfriend is such a Brosita. We we're playing Call of Duty when she got a 44 kill streak.
