Poo Leg refers to the mysterious
, involuntary spasm
of one's leg as one takes a shit
. It may be caused by the inclination to arch one's foot so that the heel levitates
above the ground. The intensity of the Poo Leg may depend upon the amount, length, or velocity
of the shit in question. Furthermore, it is possible to experience a double Poo Leg which resembles playing a double-bass drum during the into of Van Halen's "Hot For Teacher"
. Lastly, it is generally accompanied by beer shits
following the previous nights transgressions.
