An abnormal physical condition, involving the male reproductive glands, or the 'testes' if you will. It tends to manifest itself during the first stages of sexual arousal. The erectile tissue of the
penis becomes filled with blood, engorging the
penis to a semi-flaccid state. The testes at this point are withdrawn into the body by the arteria testicularis, frustrating the blood absorption process of the
penis. The
penis violently contracts as a result, contusing itself severely at the
base. The spasms will increase until the entire stem of the
penis has become purple or black-and-
blue in color. Despite the excruciating pain, seminal discharge will begin to leak out of the glans (penis tip).
It's recommended to pull back the testes immediately, despite the debilitating pain, to prevent further complications to the male reproductive organ, such as testicular torsion. (Where the blood supply to the testicle is cut off because of 'twists' in the spermatic cord.)
"Sorry mate, I'll be bedridden for the rest of the week. My
penis cryptorchismed when I made a play for the ol' ball-and-chains. She wasn't too amused... the heartless sow. Can't even walk and the wench insists that I
clean out the gutter. You got to
love her at least for her lust of the family spear."
