The exact origin of this particular om nom nom clip is unclear, as it comes from a user generated soundboard with no credited performer. The phrase itself is long established internet shorthand for cartoonish eating, popular across mukbang edits, pet videos and gaming memes. Short vocal eating sounds like this spread because they are instantly readable without context. This version stays in circulation for its clean timing and silly tone, making it an easy drop in for any joke about hunger, snacks or devouring something whole.
