An extremely beautiful girl who laughs a lot. A Brianna is always a very nice person and an amazing girlfriend.
She is always protected by a Cameron, so don't fuck with her, or else a ninja will come after you with his extreme ninja skills.
dude, I told you not to mess with Brianna, now that ninja is going to kick your ass.
