There is no single famous movie, show or viral video behind this cow fart sound, and it circulates mainly as a generic farm animal effect on soundboards and in short-form video edits. Its appeal comes from the same lowbrow humour that has made animal noises a staple of pranks and comedy sketches for decades, where a sudden bodily sound breaks tension and surprises the audience. Creators keep returning to it because it is instantly recognisable, needs no explanation and works across languages, making it a reliable gag for memes, reaction clips and lighthearted edits.
