The Taco Bell chime comes from the fast food chain's advertising, where a single bell toll has long been used as an audio logo. Online, editors isolated the bong and began adding effects, which led to versions like this reverberated edit and similar jokes such as the fart with reverb. Shared on soundboards and in short meme videos, the reverberated toll became a shorthand for mock seriousness. It stays popular because it is instantly recognisable, very short, and flexible enough to punctuate almost any overblown moment.
