Prout is the French word for a fart, and online the term has become shorthand for short, cartoonish flatulence clips shared for toilet humor. This musical version spread through meme pages and soundboards where creators collect gross-out effects for pets, bathroom jokes and prank videos. Unlike a single fart meme sound used as a one-hit punchline, or a fart button pressed for instant noise, the song format stretches the gag into a rhythm that editors can loop under a scene and time to movement, reactions or on-screen text.
