Long belch effects have circulated for years on soundboards and in cartoon editing packs as a shorthand for disgust, alongside other body humour staples like fart with reverb. This longer variant spread through meme edits, gaming streams and short comedy videos where a character needs an instant, wordless reaction to bad food, a dare or an overfull stomach. Because it needs no language or setup, it travels easily across platforms and is still used whenever a creator wants a quick, unmistakably revolting punchline without showing anything graphic.
