Fartisan

Someone who is highly skilled in the art of farting with well-developed sphinchter control that allows them to control both the duration and acoustics of their farts. A fartisan may deliberately eat certain foods in order to increase their fart power.

He possessed an uncanny ability to fart. He could release them slowly producing a fart as long as eight seconds or propel them out with one large sphinctoral push to produce a more powerful but shorter fart. He was a true fartisan and skilled fartsman.
