<human>: So at the beginning of the year I shared a room with a friend, and his other 2 friends had a room in our apartment. So that's 4 people living in 2 rooms in an apartment. 

I didn't know the other 2 guys before moving in, but they seemed like chill guys. They had already been best friends throughout college. We got along fine during the first semester -- basically no conflicts. We'd even hang out sometimes. However, at the beginning of this semester, my roommate moved out, so I have a single while the other 2 share a room. I think this is when things started to get rocky. 

At first, the two would always make passive-aggressive remarks about how I have the single, and that life sucks for them. Then, they'd start getting pissed if I ever hung out in the living room, or left anything there. Because "you have your own room, you don't need to be anywhere else here". They'd start getting pissed at me leaving a napkin on the countertop, and just the smallest things in general. On the other hand, they're the ones leaving trash EVERYWHERE, leaving drugs out in the open, leaving plates out so long that the mold is solidified onto the plates, SCREAM like animals on a daily basis every time they play video games, etc. Basically, they're the reason my roommate moved out, and they're giving me a ton of shit over small things.

I know I'm not the perfect roommate either -- I leave stuff out sometimes and may not be the cleanest. But I know for a fact that I'm much cleaner and quieter than them, and generally keep to myself. I only have a couple weeks of school left, but don't really want to deal with any extra drama. I know that if I ever get into arguments with those two, there's no way I can win, since they'll both team up against me. That's how it usually goes; when one's mad at me, both are. Any advice on how we can handle this situation?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Two best friends share room. I have a single. They're pissed about me having the single, so always lash out at me over the smallest things. How to deal?
