During intercourse between two adults, the male inserts his penis into the rectum of the female. He then proceeds to perform anal sex on the other individual until he is ready to orgasm. Once this occurs, he removes his penis from the anus of his partner and orgasms all over the female's stomach. After this is achieved, he proceeds to punch the woman in the stomach, passing the semen from her stomach to the back of his hand, and delivering a punishing backhand to the face of the woman. If executed perfectly, the blunt force of the backhand will leave the woman with a black/bruised eye. Hence, the Back Handed Panda Fist.
Geez, Dave.. i heard you gave Krista the 'ol back handed panda fist last night.
