Seinfeld, the NBC sitcom that ran from 1989 to 1998, used short slap-bass stings between scenes rather than a conventional score, and those stings became as recognisable as the show itself. As clips, reaction videos and sitcom parodies spread online, the transition riff was lifted from its original context and reused as shorthand for a sitcom-style cut. It survives because it instantly signals comedy, timing and a change of scene without needing any dialogue, making it a natural fit for short-form video editing.
