Any person who fools around on Call of Duty Black Ops zombie mode that just dolphin dives around the map, not doing anything and is the most pathetic player on the team. A Jike Mu does not benefit the team at all and instead enjoys throwing grenades at his fellow team members. He is the Justin Bieber of call of duty.
Omg stop being such a Jike Mu
Holy crap that guy is a total Jike Mu
