A method of masturbation where the flaccid penis is pressed against a hard surface such as a floor or rockery. The person then proceeds to repeatedly half pushing out a poo until an orgasm is reached but be careful not to push it out too far or you will poo yourself. This is best done with some pornography in view but can be done innocently infront of a television by watching fleshy music channels.

When you're being horny (especially around friends) and as a result shame ensues.
