mud factor

Its is a scale - generally used for the measurement of the wetness and/or lumpiness farts - It is based on a simple 1 to 10 Scale
There is a direct correlation between mud factor and skid marks.

Jimmy was horrified when the small silent fart he tried to squeeze out while on the train hit mud factor 10.
