Upper Decker

The act of taking a dump in the tank of a toilet.
Step 1: Quietly sneak into the bathroom unseen
Step 2: Carefully remove the top of the tank. Note the porcelain tank top is very delicate and will shatter if dropped

Step 3: Climb on the toilet, drop pants and sit on the tank. Imagine you are a bird sat uptop your nest, sit very softly or else the tank may break and the operation will be compromised

Step 4: Take a monster shit. I'm talkin like a goddamn mudslide out your asshole

Step 5: Whipe and throw the tp in the tank too for good measure and put the top back on

Step 6: Return to the party and act like nothing ever happened, if you leave right away you will draw suspicion to yourself
Step 7: Enjoy the host's reaction when they see that Mount Vesuvius just exploded in their toilet tank

Friend: Yo did you hear, Julia is having a party this Saturday
Me: I dislike her very much, I'm gonna drop an Upper Decker at that party

upper arm theory

The circumference of a female's upper arm can determine how much she will weigh in the future. A larger circumference predicts a woman will gain weight uncontrollably as she ages, while a smaller circumference predicts that she will keep her petite figure without much effort.

"Damn dude, the upper arm theory predicts your bitch will be fat by the time she is 30"

Classy: Prior to self ejaculation one applies a condom to his penis to release his seminal fluid, no clean up required...

Ghetto: Throw a rubber on your shit and beat the meat til you load that shit up and throw that bitch out. I ain't bout that cleaning shit.

Hey man you shouldn't keep that rubber in your wallet, it makes it less effective... No worries dude I'm just using it for a quicker picker upper (qPu)
