(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."

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.
