Not Just Smellz comes from a user-generated soundboard rather than a film, television show or widely known meme, so its exact creator and original recording are not publicly documented. Its tag links it to short fart-themed joke sounds that circulate in meme edits, reaction videos and gaming streams, where a brief gross-out gag can punctuate a scene without needing any dialogue. That low-effort, instantly recognisable humour is why small clips like this keep being reused, shared between creators and dropped into new edits long after they first appear online.
