The sound comes from Luigi's Mansion, released by Nintendo for the GameCube in 2001, where Luigi must search a haunted house for his missing brother Mario. Voiced by Charles Martinet, Luigi's nervous calls are a recurring gameplay cue as players press a button to shout for Mario. The exaggerated, frightened delivery became a favorite clip among Nintendo fans, later circulating on soundboards and in meme edits for its mix of nostalgia and comic panic.
