The riff comes from Roundabout, the 1971 Yes song adopted as the ending theme for JoJo's Bizarre Adventure, where the To Be Continued arrow became a visual meme for unfinished moments. Fans began cutting the music into their own videos, and louder, bass-boosted edits spread on meme pages and short-form video as an instant cliffhanger cue. It endures because the melody is instantly recognisable even without the arrow, much like Directed by Robert B Weide, and it turns an abrupt ending into the joke itself.
