Fisty McDonkey Punch 

When a woman with sizable hands, like that of the hammer of Thor, uses them to deal irreparable damage to her partner's colon. While in the act of fisting her partner, the woman donkey punches her partner in the side, causing the partner to scream. When this occurs, the woman shoves a McChicken into the open mouth.

I was hungry AND horny last night. It was a good thing she have me the old Fisty McDonkey Punch.

Mcdonkey

A middle aged white male who complains about everything that doesn’t go his way.
