Mario is Nintendo's mascot, first appearing in Donkey Kong in 1981 and leading the Super Mario series from 1985 onward. His high pitched greetings and catchphrases became a defining part of the games, especially in the 3D era where short voice lines play on entering levels and greeting players. Clips like this hi hi line spread on soundboards and short video platforms as a quick nostalgic cue, reused because a single greeting instantly signals Mario without needing gameplay footage or music.
