There is no verified original show, song or creator behind this clip, so it is best understood as a user-uploaded soundboard sound rather than a line from a known work. Its name comes from the noises themselves, with nibble and nom describing the eating sounds and pfffttt spelling the raspberry at the end. Short clips like this spread because they are easy to drop into edits, memes and reaction videos without needing dialogue or context. Its lasting appeal is that simple, cartoon eating humour, which stays readable even in a two-second burst.
