A useless piece of shit. He lies around all day doing fuck all. He’s overweight but never has the balls to get up and do something about it. He always has to be right about everything and will ruin a night just to try and insist he’s right when he’s clearly not. Usually ugly and weird as well, waddling around like a retard while most people try to avoid him. You can’t rely on him for anything important. A fat, useless, unattractive parasite, you should make sure to steer clear of Sebastian.
