1). Quick, stealthy appearance or escape.
2). Sneak attack from behind. In video games, often with a knife.

I was on de_dust2 and he was the last guy left, so I went the other way, pulled out my knife and ninja'd him right in the back.

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.

In chat, it is the act of saying something before someone else. It only counts if someone else actually says the same thing afterwards.

(V): When someone gives another person such a good comeback that the person being exposed to the torment never even sees it coming. But the burn does not end there my amigos. The Ninja'er comes back for a second attack, ending with their battle cry, "Ninja'd!" Then disappears before you even have time to pee your pants from shock. Here's a diaper baby, clean yo'self up. You be dirtying up my new kitchen floors. .. bitch.
Person A: "I think I was just Ninja'd and I may or may not have just pee'd a little bit."
Person B: "Ninja'd!" *Disappears*
