Slowed down sound effects became a staple of meme editing because stretching a familiar noise makes it feel more absurd, and fart sounds were an early favorite for that treatment. This extra slow version circulated on soundboards and short video apps alongside variations like fart with reverb, where creators compete to make a simple effect sound more ridiculous. It has no single confirmed movie or show source, which helped it spread as a generic punchline anyone could reuse for fails, pauses and gross out humor online.
