Ninja

In the Diablo community, "Ninja" is a term used to refer to stealing or sneaking something.

Just the word alone can mean to steal, as in, "He totally ninja'ed my item drop." The first-come-first-serve style of item drops from monsters in Diablo 2 was often called "ninja looting"

Ninja is often as an adjective with other words. For example, "ninja photos"[1][2] or "ninja gameplay footage"[3][4][5][6][7] would refer to surreptitiously recorded video footage of the game, such as might be recorded on a Blizzcon demo machine.
