The riff comes from Seinfeld, the American sitcom that ran on NBC from 1989 to 1998, where composer Jonathan Wolff used a distinctive slap bass style for the show's theme and scene transitions. Each short musical sting helped move the story from one location to another without dialogue, and over time viewers began to associate that bouncy bass sound with the show itself. As clips and soundboards spread online, editors adopted it as shorthand for awkward comedy, and it remains popular in short-form video because it instantly sets a Seinfeld-like tone.
