Megabed
Not my roommate but I lived across the hall and my best friend had to share the living space with him, I’ll call him Chad. Chad didn’t like sharing his room, so he tormented his roommate by blasting loud music 24/7, and never cleaned up after himself.
Once he got the room to himself, he took out one of the desks, and slid the two twinsized beds together to make the ‘megabed’. A week later a new roommate is assigned to Chad’s room, but Chad wasn’t willing to share, nor did he feel like communicating it with his new roommate.
Chad proceeds to leave the room a mess, and vehemently insists that “the RA’s made a mistake” and tried to explain that his room is actually a single unit, and refused to move the desk back in. His roommate slept on their living room couch during this time. Story credit: Reddit / AsianBoat69
