This sound appears to be a meme edit rather than a clip tied to a specific film, show or character. Its style comes from the long-running internet habit of taking simple bodily sound jokes and exaggerating them with blown-out, painfully loud audio. Variants like long brain fart and fart with reverb spread through short meme edits, soundboards and reaction videos because they turn even a normal visual into an absurd anticlimax. People still use it when they want cheap, sudden comedy that feels deliberately stupid.
