A term from the video game "Minecraft," in reference to its creator, Notch. Most often used as a one-word explanation for a bug.
In its Alpha stage, Minecraft suffered from numerous bugs. Despite the fact that bugs in Alpha are to be expected for any game, this did not keep some players from complaining. Whenever a bug would present itself, the common response to it was "Lolnotch."
