Deltarune is the episodic indie role-playing game by Toby Fox, creator of Undertale, with its first chapter releasing in 2018. Its battle system uses short chiptune-style sound effects to mark key moments, including the brief blip heard when a combatant is defeated. Clipped from gameplay, the sound took on a second life on meme pages and short-form video apps, sitting alongside the classic death sound in fast edits where creators need a universal shorthand for a character being knocked out.
