This sound is best known as a generic internet prank and meme effect rather than a clearly documented clip from a specific movie, show or game. Creators use exaggerated fart audio like this in short edits, reaction posts and soundboard jokes because the humor is immediate and universal. Its extra-long, overdone style helps it stand out from smaller comedy stingers such as a shocked sound or thud, so it still gets reused whenever an edit needs a loud, childish payoff.
