Replying to Annoying College Roommates

Anyone have this problem at college?

I have my roommate who was cool to begin with. He was from out of state, plays basketball, and knows a lot about video games. Beginning of first semester hes chill, watches entourage and south park on his tv. I'm fine with it because those shows are great.

As the semester moves on when we talk about a subject he always insists that he is right and I am wrong. Something as simple as "Well that video game looks fun," and he'll return with "Uh no its shit blah blah." So I can't ever talk with him. When I'm clearly trying to study he turns on his xbox and plays at the loudest volume possible and talks to himself while he plays. Also I'm a guy that gets kinda annoyed by repetitive noise, so its the end of January and being out of state he believes its warm enough for shorts. (today it was 5 degrees).......so he gets sick.

Now I'm sitting at my desk doing my own business making no noise while my roommate is coughing hard like hes trying to force a cough every 5 seconds, while talking to himself, while playing xbox at max volume.... every single day.

Normally I'm a nice guy so I deal with it, but now I just can't stand it. And on top of that, his side of the room is dirty as fuck with old boxes and garbage and he never cleans it. So next semester I'm getting an apartment with my friends who are normal.

Anyone else face the bad roommate problem?

tldr: roommate is really annoying, how bout you?
