Burp sounds have long been a staple of online comedy because they are instantly understood, need no context, and work in almost any language. Short clips like this one circulate on soundboards, where creators save them for quick reaction moments rather than full jokes. At under a second long, it fits easily between dialogue, over a reaction shot, or at the end of a failed attempt, which is why editors keep returning to it for low-effort, high-impact humour. Its simplicity is also its staying power: the gag never needs explaining, and it lands the same way every time.
