The Taco Bell chime comes from the chain's advertising, where a single bell toll has long served as its audio logo. Online, editors pitched and layered that short sting into a mega version with exaggerated reverb, and the clip spread through meme soundboards and short-form edits. Its humor relies on contrast, applying a cathedral-sized toll to tiny, trivial moments. Because it is instantly recognizable and only about two seconds long, it remains a popular drop-in effect for reaction videos, stream alerts, and ironic announcements across social platforms.
