My roommate and why he sucks

So last night its about 1 am so im going to call it a night after playing a few games of madden with my suitemates. Im just about falling alseep and he comes into the room yelling. So I have a few choice words for him so he leaves. This I did not have to much a problem with but some of the things he does i will vent on here about because I dont want to be a dick. I dont think this kid has done laundry since he has been here he just wears the same clothes which is just sick so when he is not in the room i febreeze the shit out of the room and it just happens to get on his clothes. I want to say something to him but i do not know how to do this in a kind way because im fed up with it. There are a few other things he does but I dont feel like talking about him anymore. Any suggestions if anyone reads this???
