(n) A dirtbag of total douchery. Will Often steal credit for other people's hard work, never on time, calls others dirtbags to deflect their own dirtbagedness. If a Douchemont was in an army, he'd totally fuck his buddies every chance and talk shit behind their backs. Probably takes pills to make them less crazy, but the pills obviously don't work. Enjoys going down dark alleys and sucking off homeless chinese men against their will.
