This is a very brief fart noise, lasting less than half a second, with a low, blunt burst that lands and stops almost at once. It feels crude, silly and instantly funny, the kind of sound that makes a quiet room crack up because it is so sudden and rude. It works best as a quick shock gag, not a long joke.
