The clip is best known online through soundboard pages and searches for a metal crusher download connected to Undertale, the popular indie role-playing game, rather than as a widely documented track from its soundtrack.

Its eighteen-second length gives creators room to cut the strongest crunch, and its continued use comes from that practical flexibility, not from a single viral video.
