This tone was made by creator DubstepDentist for a livestream audience, so viewers could hear the new SMS sound together when it was introduced. Rather than coming from a film, game or viral meme, it started as a small custom alert shared with a streaming community. That personal, stream-first origin is part of its appeal, as listeners pick it up to recreate the same in-joke on their own phones. It remains useful because short, distinctive notification sounds are easy to recognise in a busy feed.
