The format comes from JoJo's Bizarre Adventure, whose episodes end with a To Be Continued arrow over a freeze frame, accompanied by the opening of Roundabout by Yes. Short form editors on Vine borrowed that ending for fails and awkward moments, trimming it to a few seconds and keeping only the arrow and musical cue. The To Be Continued JoJo version became the template, and the Vine cut spread to YouTube and TikTok as a reusable cliffhanger sound that needs no setup to be understood.
