When two people have to poop simultaneously, so one person sits the the lap of another while facing each other on the toilet. If it’s a boy and girl and they are having vaginal intercourse while double decking, it’s called docking the buses.
Yesterday my bro and I had to both poo, but the spare bathroom was close. We ended up doing a double decker, luckily the bowl didn’t fill up.
My girl and I had to drop a deuce so we double decked. She’s got them big boobs though, so after a minute we docked the buses ;)

Performing a European Double-Decker involves a male and female deficating in the bowl and resevoir (respectively) with the male straddling the resevoir, thus giving him access to perform cunnilingus on the female.
Brad and Angela just got back from a European Double-Decker in the bathroom. You can tell by his white mustache and brown soul patch.

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.

When you and your bro have sex with two separate girls on the same bunk bed. One on the top bunk and another on the bottom. When done properly the shaking of the two beds off set each other perfectly.

The act of two people pooping on the same toilet at the same time.
Typically, this requires one person to sit on the toilet seat like normal, and the other person to sit on the lap of the first person, using their legs as a typical toilet seat and aiming for the whole between said legs.
