This term can also be used when referring to someone that is soooooo beast at Black Ops.
Person 2: If you think Black Ops is so awesome then it technically is Beast Ops!
Person 1: Man while playing Black Ops last night, (insert PSN name here) kept killing me with a sniper on Nuketown!
Person 2: He must have been playing Call of Duty: Beast Ops instead of Black Ops. They both connect to the same servers though.
