Ninjad- the verb form of Ninja

1. v. The past tense form of taking an item from a person without their noticing, usually right in their line of vision.

2. Used in the popular game "Halo" for xbox 360 when a player is getting chased down by another from behind, jumps backwards, and assassinates the enemy. (past tense)
1)
Person 1: Where did my gum go?

Person 2: Bob totally ninjad it from you when you were playing basketball with him.

Person 1: Damn it, he is always taking my gum.....

2)
Player 1: How'd you kill that guy when he was chasing you and unloading bullets into your back??

Player 2: I totally ninjad him, he never saw it coming.

Player 1: ohhhhhhh, what a noob....
