The file itself is tagged Whistle by Samsung, which points to the stock notification style shipped on Samsung Galaxy phones rather than a meme or show. Short phone alerts like this get ripped and reuploaded to soundboards because they are instantly recognizable and useful in edits. Creators making short videos reuse the whistle to simulate messages, notifications, or attention grabs without recording their own phone. Its continued use comes down to familiarity: almost everyone has heard a tone like it, so the joke lands in under two seconds.
