A distinctly intricate compound fart, characterised by an extended succession of harmonious 'trump' elements in an unusual composition. Comprises of more than three individual tones, which when blended together audibly- form a piece of gaseous music from one's anal passage.
A difficult skill to master, involving the contraction and controlled blowing of the anus. Usually apparent after ingestion of pro-methane-production food stuffs, such as Protein Shakes, JRAC Food or the consumption of solid effervescent tablets.
When more than one "Sphyncphony" is played from several anii (anus, plural) , this is commonly known as an Orchestral Sphyncphony, or a fucking smelly disaster.
An unforgiving volume of odour-rich methane gas is usually a bi-product of a Sphyncphony. Volumes of gas have been recorded to fill a 5 person bedroom.
Repels all female species and may be used as a room-mate deterrent.
After a succession of farts
, *Laughs* "Holy shit
, that was a Sphyncphony! A LOVE IT"
"I need a trump
..." *performs sphyncphony
and pisses off Rick* - "You smelly bastard"!
"Pull my finger
..." *tugs left index finger
* - cries with laughter due to sphyncphony.
