Mukbang began as a South Korean online trend where hosts eat large amounts of food while talking to viewers, and it spread worldwide through YouTube and TikTok in the 2010s. Short eating clips were later cut down for memes and soundboards, separate from the long livestreams. This guy version has no confirmed source video, so it circulates mainly as a reaction sound alongside other munch eating biting clips. Creators reuse it because the chewing is instantly recognisable without any context, making any ordinary meal look like a full mukbang performance.
