A situation in which a video game (usually produced by Nintendo) leaves you in a state of being unable to survive, complete a level, or interact with the game, usually resulting from a bug in the game's software. This state is known for being most common in old NES games, such as Super Mario Bros. 2 and Metroid.
When I jumped into that wall in Super Mario, I got Nintendo'd because I couldn't get out of it and had to restart the game.
