This sound is mainly known online through Roblox meme edits and short joke videos rather than from a clearly documented original scene. Creators use it as a cartoony eating cue for avatars, pets and food gags, often in fast cuts or reaction-style memes. Its staying power comes from how instantly recognizable the chewing idea is, even in a very short clip. It fits the same broad family of goofy ahh sounds that editors use to exaggerate simple actions and turn them into punchlines.
