A guy I dormed with for a year was the same way, but not to that extreme from what I know. He was an asshole and his family had money, would just party the whole time. My whole room would (with the exception of me of course), but he was always to the extreme. He eventually got expelled from the school for getting written up too much. Then one day he snuck back onto the campus to go to more parties, and ended up punching some woman across the face. Security saw him, chased him down, and tackled him on the field. I transferred to another school after that year, because fuck all that bullshit. He ended up graduating from someplace else and getting a pretty good job despite all this, probably because his family had a bit of money. He's dead now though at 24, it's a pretty safe assumption from what.
