When performing anal sex, when the male pulls out and feces is coagulated on the tip of the penis, the male then wipes the coagulated feces on the inside of the female's buttcheeks. When the female discovers the disposed of coagulated feces on the inside of her underwear, it is known as an incisor hershiser.
