Brennan

Brennan can used as a proper noun, adjective, or verb. He is sometimes used as a secret hand shake, a put down, or maybe just a person in your school. The music he listens to is hard-core country, rap is NOT tolerated so when you're near a Brennan, be careful on what radio station you put on. Friends are not a big part of a Brennan's life except for his best friend, Caitlyn D. His name is also substituted for normal words in many songs.

Boy: Hey babe wanna go play yahtzee?
Girl: GO BRENNAN YOURSELF!

2 friends: rock paper scissors says brennan!
