shitstopper 

A shitstopper is when you thrust your knee with power to hit someone's arsehole. Therefore this is said to stop your shit.

Shitstopher Reeves 

When you take a shit for so long that you make your legs go numb. When you try and stand up you fall onto the floor.

Dude i sat on the toilet so long last night that i pulled a Shitstopher Reeves and smashed my head off the floor.

Sheboygan Showstopper 

The Sheboygan Showstopper is a sexual act in which the man inserts his penis and testicles inside a woman's (or man's) anus. The testicles will often become stuck inside the anus.

We were having butt sex when I accidentally gave her the Sheboygan Showstopper. I couldn't get my sack back out.

I needed to get home to have dinner with my mother so I ended her with a Sheboygan Showstopper

shitstomper

One who takes a dump in the shower, then spends the next several minutes stomping it down the drain with his/her foot. This term is particularly relevant when the shit log squeezes up between the toes during the initial stomps.

The toilet was broken at our hotel so I had to pull a shitstomper.
