My worst is a glam-rocker. He's slightly chubby, yet is obsessed with Towers of London and seemingly any style over substance shit, so wears skin-tight clothes. He insists on walking around topless (obviously breathing in), he's loud and obnoxious and screams when he comes in at 4am. He has an Asian girlfriend, and is racist when she's not in the room.
He's the most awful human being I've ever met in every single possible way, and I'm counting the seconds until I move out and never think of him again.
If you have your own, misery likes company...
