Mario is Nintendo's mascot plumber, starring in the Super Mario series since the 1980s, with his cheerful voice defined for decades by Charles Martinet. Short voice clips of the character saying yes, no, woohoo and similar exclamations circulate widely as reaction sounds across YouTube, TikTok and meme edits. This particular denial is popular because it is instantly recognisable and completely nonverbal in feel despite being a word, so it works across languages. Editors keep reaching for it whenever a clip needs a fast, friendly rejection without any setup.
