Mario is Nintendo's famous plumber and the star of the Super Mario series, and his upbeat ya-hoo has become one of his most recognisable vocal catchphrases across the games. Players first heard his cheerful voice lines in the 3D era of the series, and clips of them soon spread through gameplay videos, edits and memes celebrating wins and funny moments. Alongside the classic Mario Jump sound, it remains a shorthand for success in gaming culture, instantly understood even by viewers who have never played the games themselves.
