Ninja'd 

A new tactic the the FPS Xbox 360 game, Halo 3. A Player lures another player into following them. Player 2 is following player 1. Player 1 goes around a corner. Player 2 Follows. Player 1 jumps backwards, and Player 2 passes under Player 1. Player 1 Melee's Player 2 and instantly dies due to an assassination. Ergo, Ninja'd.

Blue Player: "YOU JUSt GOT NINJA'D!"

When someone takes something or someone away from you and you did not know whats the fuck is going on until the person ninja'ding you is laughing his/her/ ass off. The term ninja'd is usually mixed up with thiefed but the stupid sob that did that is spread across the atlantic ocean....Right now.

During the 2020 Covid crisis, and after roughly 1.5 months of quarantined groups of people began to ninja people. To be Ninja'd means that someone dropped a wine, whiskey, cannabis or even toys and candy to a random stranger to being cheer during a time of crisis.

I went out and Ninja'd someone today.

Have you been Ninja'd yet?
