Galveston double decker

The act of two people pooping on the same toilet at the same time.

This typically requires one person to sit on the toilet seat as usual, and the second person to sit on their lap, using the legs of the first person as a toilet seat and aiming for the gap between the legs.

“There is nothing Gay about a Galveston Double Decker”

“It was an emergency and there was only one toilet, so we pulled off a Galveston Double Decker”

double fender decker

when you earn 10 bucks, so you try to double it for 20, but then someone robs you by hiding your earned money in an electric guitar.

Person 1: Hey, I’m pretty sure my money got stolen last Tuesday by that guy with the fender guitar

Person 2: Someone probably pulled a double fender decker on you then….

Upper-decker Double Blumpkin

A dude sits atop the toilet tank and craps in it, facing forward. A woman (or man, I guess...) sits on the toilet backwards and also crals as s/he performs oral sex on the guy seated atop the tank.

What were you two doing in the bathroom so long?
I expelled every fluid imaginable thanks to getting an upper-decker double blumpkin.
