Similar to Upper Decker; Only, instead of doing it in upper part of the toilet, you open the door to the person's Clothes Dryer and take a juicy dump, close the door, and turn the dryer on "High Heat". Walk Away smiling as you hear the distinctive "thump thump" sound. Only do "Dry Deckers" to people you don't want as future friends.
"Yeh Man, he made me so mad, I left him a Dry-Decker. When he found the dryer running a 1/2 hour later and opened it up, he realized he would have to throw the dryer away."

When someone poops in the top part of a toilet, (the part that you have to take the top off) so when someone else goes to the bathroom and flushes the toilet instead of clean water coming in and filling the toilet, shit water comes in. This is done as a pratical joke, usually done at parties.
Guy 1:Hey I just did that Upper Decker in the toilet upstairs and Jennifer went in there.
Guy 2:Hahahah, what'd she do when she came out?
Guy 1:I don't know, she's still in there!
Guy 2:Hahahah, what'd she do when she came out?

The act of taking a shit while another is sitting on your lap and shitting simultaneously between your legs.
Perry and Carl both had to shit but only one toilet was available so they performed a double decker.

The act of sitting in ones lap while he or she is sitting on the toilet. The individual on bottom produces excrement into the bowl of the toilet while the individual on top produces excrement between the bottom individual's legs thereby creating the "upper" portion of the deck.
*Often confused with an UPPER DECKER, in which one individual produces excrement into the upper tank of the toilet.*
*See also: Upper Double Decker

Roommates Ezekiel and Jebediah both consumed too many matzah balls and were locked in a heated stand-off over who may use the toilet first. They decided to compromise and perform a DOUBLE DECKER.
