This is a generic reaction sound rather than a clip from a named film, show or viral video, so its exact origin is unclear. Short fart sounds have long been a staple of comedy editing, prank videos and soundboards because they need no context to land. This version stands out for its uneven delivery, starting quietly and then getting much louder, which makes it useful as a delayed punchline. Online, creators reuse it in memes, gaming clips and short-form videos whenever they want a crude, immediate laugh.
