The microscopic particles of poo dust created when farting. It is actually these airbourne bits of turd that carry the tender scent and sometimes even the subtle taste of shart through the air and to your senses to enjoy.
Laughing heartily at Earl's huge fart I accidentally received a dank and grimy mouthful of whiffle dust. It was then that I realized Earl had boiled eggs for breakfast.
