A player in World of Warcraft who rolled the class of Death Knight because in the earlier levels they are OP and easier levels. By earlier levels, I mean level 55-68, because they are for retards who don't want to level another character from level one. Once they are 80, they run around in randoms like dumbasses and drop Death and Decay everywhere. The Death Knoob will then say Lawl, yous gots pwnedz0rs, and leave.
Person that isn't a retard #1: Is that Death Knight Dual-wielding in Blood spec?
Person that isn't a retard #2: Yeah, he's a Death Knoob, mosdef.
