look up any word, like cunt:

1 definition by blackpearl905

The act of two people, male or female in any combination, rubbing their anus' together for the purpose of sexual gratification.
My wife makes me take a shower to remove my duck butter before long sessions of port holing.

After a long workout there is nothing quite as gratifying as the sweet surrender of port holing my best friend.
