I never heard of anything like that for Call of Duty, but there is a game coming out in 2009 for PS3 only called MAG, which stands for Massive Action Game, that is supposed to support up to 256 players in one game.

it refers to the grenade launcher attachment you can put on assault rifles. They are usually 1 shot kills and take little skill to use, hence the nickname.

CoD 6 hands down
