The chime comes from Taco Bell restaurant branding, where the bell logo has been central for decades and its deep bong became instantly recognisable in television adverts. Online, editors isolated that single hit and turned it into a standalone meme sound effect. It spread through YouTube compilations, gaming edits and short form videos as a shorthand for a dramatic reveal or a stupid mistake. Its popularity lasts because one clean note needs no explanation, works at any volume, and pairs with almost any visual punchline without extra music or dialogue.
