My room is pretty clean right now, but only because my mom gets fed up with me not cleaning it and does it for me. You normally can't even see the floor beneath all the clothes and books and paper and trash.
My desk area is by far the messiest, since I tend to spend a lot of time sitting there. I have the habit of just putting anything anywhere on top of the desk - plates, paper, wrappers, bottles, anything - and yeah, it tends to build up after a while. Usually takes some time before I look at it and finally go "yeah, that's too much, time to clean up."
Most of the rest of this apartment is clean. Ish. Relatively. Okay, maybe slightly. Far from spotless, but nowhere near as cluttered as my desk is.
(I probably should clean it soon, especially if I'm planning on actually getting that new desk I wanted...)
My bedroom is really messy. My parents separated and moved out of the (big!) house that I pretty much grew up in for the last ten years so over the holidays I had to pretty much take all the stuff I wanted to keep to my place at school and I haven't really found a place for it because my living space is much smaller here. So I've got piles of stuff all over my floor and I just haven't found the time/drive to deal with it yet. But my mess is mostly contained to my bedroom/basement area. No food or anything--I'm not gross, I'm just not very good at containing my clutter, especially when I have more stuff than room to put it. XD;
My roommates aren't the tidiest people ever so we often let things get really cluttered but eventually one of us will get tired of it (or we'll have guests over) so we'll spend an afternoon just cleaning up and tidying. We do that maybe once a month so it's never so cluttered that it's disgusting to live in or anything. :P
I do find my room kind of stifling when it's this cluttered, though. I really need to deal with it soon so I have space to actually walk around.
My room is so messy it's like a tornado hit it. (Or that's how my dad puts it.) I have to share it with two other brothers so it's full with all of our clutter combined. It's mostly my older brother's stuff cause he leaves all his papers, drawing and pictures he printed off the Internet on the floor and he has at least 100 or more of them. I can't wait to have a room of my own, I'd probably keep it a bit more tidier.
