Nicky: Oh yeah? You do such anal things as ironing your underwear!
Rod: You make that very small apartment we share a hell.

Living with other people can be hard. Even if they're your friends, you may not like the way they fold their towels or clean their dishes, and Heaven help you if they decide to bring their dates home. And, this can be even harder if the roommate is someone you don't get along with in the first place, or just generally clash with.
Common plotlines that ensue with this trope involve the roommates fighting for space, one of them being absurdly annoying or otherwise difficult to live with, and a major difference in personalities that cause both of them to be fighting, such as one of them being a slob, and the other a neat-freak. It can occur between enemies, strangers, or even people who are otherwise best friends, discovering their differences while Hilarity Ensues.
They may learn to live together and become close friends, or the bad roommate will need to be escaped from by any means necessary; otherwise, the hilarity and drama will continue indefinitely.
Can overlap with Roommate Com, if the characters living together is the work's premise, and contrast From Roommates to Romance, where the premise is that the roommates fall in love as a result of living together.

"Goddammit Diamondback, shut your fucking alarm clock off!" The illusion shattered and I open my eyes to realize the devil's laughter actually belongs to the beeping of the most obnoxious alarm clock known to man, the voice to a girl I had come to know and loathe.
