When you are taking a shit in the upper tank, she's giving you a blumpkin while taking a shit in the bowl.

The double decker is a combination of the upper decker and a blumpkin. The guy is on the top tank performing an upper decker while the girl faces the wall with her feet on the toilet seat giving him a blumpkin while she drops a deuce in the bottom tank

When taking a shit, having someone sit on your lap aiming their anus between the first person's legs. Both people shit at the same time, creating a "double" effect and saving water in the process. For utmost efficiency, time the splashes similar to Olympic synchronized diving.
