The line comes from Super Mario 64, released for the Nintendo 64 in 1996, where Mario defeats Bowser by grabbing his tail and spinning him away. Players widely misheard Mario's farewell as 'gay Bowser', and the phrase became a long-running internet joke shared in clips, remixes and forum posts. Its playful misunderstanding, rather than any official wording, kept it alive, and creators still use the short audio as a nostalgic nod to early 3D platforming and classic Nintendo humour.
