This kind of chewing sound is a staple of generic sound-effect libraries rather than a clip from a famous film or show, and it circulates online as a reusable eating noise for short-form video. Creators favour the longer version because it gives them room to time a bite, a reaction or a joke without cutting to a new clip. It is still used for mukbang edits, prank videos, ASMR-style posts and animated eating scenes, where a realistic mouth sound sells the moment better than music or dialogue alone.
