The line comes from Super Mario 64 DS, Nintendo's 2004 remake of Super Mario 64 for the Nintendo DS, where Mario speaks short voiced phrases throughout the adventure. Charles Martinet provided Mario's voice for the era, including this goodbye heard when quitting or finishing. As clips from Nintendo games spread on video and soundboard sites in the 2010s, the buh bye was isolated as a standalone reaction sound. Its brevity and familiarity made it a lasting choice for edits referencing Nintendo and retro gaming.
