A high and low measurement of the thickness/solidness of one's feces. High Fecal Viscosity means constipation. Low Fecal Viscosity means loose, watery stool.
Roger was urinating in the men's room when he heard the man in the handicap stall suffering from low fecal viscosity. He was taking a mop bucket dump.
