Noodles Doody-Decker

When the styrofoam floatie-toy in the pool isn't styrofoam and definitely is not a toy.

The lifeguard at the pool was nodding off, so I figured a Noodles Doody-Decker would cause a commotion, and just might force him back on duty.

upper decker

To put toilet paper over someone elses poo when the toilet is clogged and then take a shit on top of the original poo.

I shit on eric's poo because he clogged the toilet and there was nowhere else to go.

Double Decker Blumpkin

the act of a male individual shitting or pooping in the upper deck of the toilet while a girl goes down on you (aka; sucking your penis), while she releases poop out of her butthole into the lower deck bowl of the toilet.

Jeff to Randy: Dude, bro, Jerry definitely just got some of that double decker blumpkin action dome piece from that random B with the STDs.
Randy to Jeff: Real nice, real fuckin' nice.

Double Decker Blumpkin

When someone is doing an upper decker and the person on the lower decker is is giving head and takeing a shit at the same time.
