The clip comes from Mario's voice line during Bowser throws in Super Mario 64, released by Nintendo in 1996. Over time, players widely misheard it as "So long, gay Bowser," and that mishearing became an internet in-joke shared in videos, remixes and soundboards. Its lasting appeal comes from the contrast between Mario's cheerful delivery and the weirdly aggressive phrase people think they hear. It still shows up in gaming memes whenever a character is tossed away or decisively beaten.
