Deltarune is an indie role-playing game by Toby Fox, first released in 2018 as a follow-up to the world of Undertale. Its battle encounters open with this short cue, signalling the shift into the game's turn-based combat where players can fight, act or spare enemies. Clips of the cue circulated among fans on video platforms and soundboards, where it became shorthand for starting a confrontation in edits unrelated to the game itself. It remains popular because it is instantly recognisable to players and short enough to work as a clean transition.
