Deltarune is an indie role-playing game by Toby Fox, first released in 2018 as a follow-up in spirit to Undertale, with turn-based battles at the centre of its gameplay. Short cues like this one became easy to reuse because they are instantly recognisable to fans and carry the game's retro, chiptune-influenced style in less than a second. As gameplay clips, memes and fan edits spread online, the battle cue moved beyond the game itself and became shorthand for an upcoming fight, challenge or confrontation in short-form video.
