Dirty DelDuco
Usually takes place when your partner rejects you for sex. The rejected person waits until their partner is on the middle of a massive shit. At just the point when your partners legs go numb from being on the toilet so long you break in and force yourself on them. Generally your partners legs are so numb they can not close them. The utter shock of you busting in has also rendered their arms useless. This is a sneak attack so you must climax quickly before your partner realizes what is happening. It should as also be noted that the longer you take, the more likely you are to get covered in pooh.
I don't know what going on with my wife and I. If she doesn't give me some soon I am going to have to give her a Dirty DelDuco.
