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.

Decker Side Bandits

A name for group of Asians who have now grown in numbers, reside in the heart of Little Seoul. They are known for their ruthless behavior and violent murders. Decker Side or D-Side is one of the largest Asian street gangs in Los Santos.

Little Seoul is known to reside mostly of Asian descent. After the riots took place in 1992 Asians had to band together and protect their home, that would also be known as China town.

This is from the mouth of a women who resides on Ginger Street. "I've watched most of those kids grow up and I know most of their parents, it's sad to see the violence that takes place in Little Seoul, but we feel safe when Decker Side Bandits are outside, they are still humans and have hearts".

Double Decker

A Double Decker is the action of one removing the top of a toilet, and proceeding to take the actual fastest shit in the top toilet, and leaving it floating like the fucking Titanic.
Double Decker are usually meant to either torment or assert dominance by defecating inside of the toilet.

My friend always asks to use the bathroom, every-time I say “ Don’t shit in the top of my toilet”.
Then he says “I’m not going to”.

Then he Double Deckers me, and I find it a week later because my bathroom develops the most malevolent smell.
