This sound is associated online with Undertale, the 2015 indie RPG known for its distinctive retro audio style. On soundboards and short-form video platforms, creators use the clip as a shorthand for disappearing, despawning or abruptly ending a moment. Its popularity comes from how quickly it communicates a visual removal while still sounding playful and game-like. Even outside Undertale-specific edits, it remains useful in meme videos because the effect is short, readable and easy to sync to a sudden cut.
