A combination of the infamous "Upper Decker" and "Dry Dock". First, shut the flow of water off to the toilet by turning the valve on located low on the wall facing the back or side of the toilet. Then flush the toilet ensuring all the water gets flushed out. Then, remove the lide and defacate inside the tank and re install the lid. If you have a particularly large bowel movement or a partner you can defacate in the bowl as well for a traditional dry dock. This creates a highly concentrated sometimes lethal dosage of stink when the tank lid is removed so the tank can be inspected. Also known as the "Dry Deck". This should only be used in when absolutely neccessary. Or when staying at a freinds house.
Jason nearly passed out when he went into his bathroom and discovered the stink tank I had left behind for him. Afterwards, he became irrationally angry.
