An extremely beautiful girl who laughs a lot. A Brianna is always a very nice person and an amazing girlfriend. She is so amazing and perfect and fun to talk to. I love her. Brianna tends to get distracted very easily.
She is always protected by a Joey, 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.
