He has two modes of conversation: all the girls he's had sex with and all the shots he took last Saturday.

He gets into fights at "da club" and then either tweets about it goes on a Facebook rant about people "who mess with his boys."

He live tweets and/or live facebooks sports games as they are happening
He has posters of half-naked chicks on his wall.
