The line comes from Xigbar in Kingdom Hearts II, the action role-playing game where he appears as a member of Organization XIII. His laid-back, mocking manner made many of his lines memorable to players, and short clips of his dialogue later circulated on soundboards and in fan-made edits. Creators keep returning to this one because it works outside the game too: it needs no plot knowledge to understand, and its sly tone instantly signals that someone is being sneaky, caught, or about to be outplayed.
