I finally figured out what that smell is.
It's the dog damn kitchen sink. When looking for the source of the smell I took a whiff of the contents of the kitchen sink, almost puked, and ran coughing back to my room. I don't even go in the kitchen anymore because of stuff like that, so it's not my problem. But every time I go to my room, I can smell it and it's really pissing me off. It's mostly old, slowly fermenting rice. But other things as well. Ugh >_<;
