[header] How to fart quietly [title] Release the fart slowly. [step] Rather than release the fart quickly, which will likely cause a loud fart noise, take your time and release the fart slowly. Do this by squeezing your abdominal muscles and taking long inhales and exhales as you release the fart. 
Releasing the fart slowly should cut down on the noise it makes as it comes out of your butt. Or spread your buttcheeks as far as you can from each other to make a smooth, wavy fart that can sometimes have no scent at all.
