Black Ops Zombies. Name given to the mini game 'Nazi 'Zombies' in the PS3/X-box game 'Call of Duty: Black Ops' (which was really and truly over-rated) Nazi Zombies (Zombus Vulgarus) is a sweet-ass game created by Treyarch and consists of 'endless waves of the undead' and you have to fight them off with weapons such as; Ray-Gun, Pistol, Assault Rifles etc. Blombies is used to identify which game you want to play (being it CoD:WaW or CoD:BO) therefore, time-saving and effective. It also doesn't sound as 'harsh' as 'zombies', where-as 'Blombies' rolls off the tip of your tongue.
