Variation on upper decker. Instead of shitting in the tank of a toilet, shitting in the bowl and then manually repositioning the load to the tank.
I was so drunk I forgot to do an upper decker, but after I saw the sweet log I fired into the bowl I knew I had to go for the ground rule double.

Get the ground rule doublemug. I hit a ground rule double yesterday. First I did the blonde, then later that night the redhead droped by for a booty call!
