Taco Bell has used a short, distinctive bong as part of its brand identity in commercials and in-store audio for many years, which is why listeners recognise it instantly even outside a restaurant. Online, creators lifted that familiar chime into short videos, reaction clips, and food memes, where it became shorthand for a craving, a late-night run, or a joke about fast food. Its brevity makes it easy to drop into edits, and its association with affordable, indulgent meals keeps it relevant whenever hunger or a drive-thru joke is the punchline.
