This sound comes from SML, the long-running YouTube puppet comedy series centred on Mario and his unruly adopted son Jeffy, whose childlike behaviour and toilet humour made him a breakout meme character. Episodes built around Jeffy often lean into exaggerated disgust, and short reaction moments like this one travel well beyond the original video. Clips are reused on soundboards and in short-form edits because the joke is instantly recognisable even without context, keeping Jeffy’s gross-out style alive for new audiences.
