The name refers to Nestlé Crunch, the crisped rice chocolate bar first sold in the United States in 1938, which became known for its distinctive snap when bitten. Short crunch clips named after the bar circulate on soundboards because the texture is instantly recognisable even without picture. Creators reuse the bite as a shorthand for craving, satisfaction or over the top eating, and the added numbers in many uploads are just file naming from repeated shares rather than a separate version or official release.
