An often audible, and aromatic expulsion of intestinal gas via the anus. The sound is produced by vibrations of the anal opening. Frequency, pitch and volume depend on the velocity and volume of the expelled gas and the tightness of the sphincter muscles of the anus. The degree of discomfort experienced by those who perceive the smell of the peo is affected by the following variables:
* Proximity to the anus letting the poe rip.
* Familiarity to the person expelling the peo. Peos from strangers are much more sickening.
* Amount of egg and beans eaten in the last 24 hours by the person who let the peo go.
