Luigi is Mario's taller younger brother in Nintendo's Mario series, a character known for being nervous and easily frightened despite starring in games like Luigi's Mansion. Short clips of his panicked yells have circulated on soundboards and in video edits for years, often grouped with other scream meme sounds and goofy ahh sounds used for comedy reactions. Because this scream is so brief and recognisable, creators reuse it as a generic cartoon panic cue far beyond Nintendo gameplay, pairing it with falls, chases and surprised faces.
