Unlike a clip taken from a film or show, this is a generic user-made soundboard effect with no single known origin, which is typical for short fart sounds shared online. The joke works because fart noises are a long-running staple of slapstick and internet humour, and adding reverb gives an old gag a fresh, over-the-top scale. Creators reuse the echoing version in short-form videos, reaction clips and prank edits because the lingering tail makes the punchline land harder than a dry, brief blast.
