you seem a little uptight about it, but from what you have said he does seem to be a dousche bag, i lived in the dorms the first two years, and loved it, the first year i was in a quad at osu, which sucked big time, me and the roommates got aggitated by each other, but they were good guys so nothing was too big of a problem that we wouldn't just say something about, just say something and if he is a dousche move out
and dude you really got to get rid of the high school guidance teacher poster for destiny
