Upper Decker

The act of defecating inside the water tank of a toilet.

Step 1: Go to the home of your mortal enemy. Ask to use the bathroom.

Step 2: Approach toilet and remove the water tank lid.

Step 3: Step on the sides of the toilet and squat over the water. Carefully take a massive dump. Wipe your ass and dispose of toilet paper in the trash bin.

Step 4: Place water tank lid back on the toilet.

Step 5: Escape.

What happens? With each resulting flush, it will fill the bowl with a chunky brown water. Its the gift that keeps on giving :)

Double Decking

Taking a dump into the toilet tank so when a person flushes the toilet they are astonished to see a turd come down.

Marlene was shocked at the Omega Mu House party when she flushed the toilet and a big nasty frat boy turd came down and she realized that she had been the victim of double decking.

(WARNING: Do not try this. You could easy break a toilet. )

Double decker

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.

She sat on my lap while I was on the toilet so we could double decker that shit.

dick decked

When you get hit in the eye so hard by a dick, it looks like you got punched.

Ashley has a swollen eye because she was dick decked by Ryan.

Double Decker Pecker Wrecker

The act of slobbering on a fat dick that is so big it makes you drool. It tastes good like chocolate so you want to have all of it. You’re ability to take all of the Dick with ease relates to it being a pecker. You make the guy feel so good that his Dick feels wrecked and used.

Lucy gave me a double decker pecker wrecker last night. She’s a keeper
