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.

The scenario is such that you have a kiss and a promise from your old lady but you are not confident that she will deliver later on. So you have the forethought to masturbate in the morning so if it dosent work out with her later you don't become a testosterone filled mad man. So contrary to a double header which would require one to have sex twice in one day this would be considered a Ground rule double should she conced to sex later on.
Person1: Hey Keith I scored a Ground rule double yesterday.

Person 2: What the hell is that?

Person 1: You know it's when you rub one off in the morning and score with the old lady at bedtime.

Person 2: Oh yeah I did that last Sunday.
