The clip comes from competitive eater Matt Stonie's 2L Diet Coke challenge, titled No Burp, where the challenge is to drink two litres of Diet Coke without burping. The long burp is the moment that tension breaks, which is why the audio was clipped and shared on soundboards as a standalone reaction sound. It spread through short-form edits, prank videos, and meme compilations that needed an instant gross-out punchline. It remains popular because the sound is unmistakable, easy to recognise, and works without any visual context.
