ninja

incredible game in which players bow toward one another to start the game and then each player makes one move at a time, in a clock wise manner. the object of the game is to hit the opponent(s) hand. the last person standing is declared the ULTIMATE ninjaaaaaaaa...
these games lead to awkward positions by all players, most of the time very homosexual.

often a lunch time pass time for jasons, manuels, sebastians, and franciscos.

Person 1: dude, what do you want to do?

Person 2: lets play Ninja!

Person 1: hell yeah!

Halo Player 1: Why are we in theatre mode?
Halo Player 2: I just have to show you this awesome Ninja I pulled on (Insert Pro Gamertag) last night in MLG.
Halo Player 1: Is it anything like the other 6 you have in your Fileshare already?
Halo Player 2: Better..
