While engaged in anal sex, a punch delivered to the back of the woman's head such that her anus contracts, intensifying the pleasure. Not unlike a Donkey Punch, but with more ferocity and force.
Dude...I was fucking A.M. in the ass last night and got bored so I Dorse Punched her! Right on Time, Yo! Holla! LOL!
