This sound comes from Taco Bell advertising and became widely recognized online because the bell chime is so short and easy to drop into edits. Over time, creators turned it into a reaction-style audio cue for food jokes, sudden reveals, and ironic endings. It stays popular because listeners identify it almost instantly, even when it appears for less than two seconds. In meme culture, it often fills the same role as a buzzer or a quick sting that marks the exact beat of the joke.
