Cinder Block Sit Down

A sexual act were a funnel is lodged into one partner's sphincter while laying face down making a 45 degree angle with their body. The other partner then proceeds to poor cement into the lodged funnel. This causes a chemical reaction with the rectum and begins to solidify the cement into hardened concrete. After undergoing surgery a perfect mold of the human rectum as a result.

Poor Sam couldn't handle the cinder block sit down, but now I have this nifty paper weight.

sending mandela down the river

Taking a large dump and flushing the toilet a few times to get the entire contents down the pipe

"Where's Tony, we have a meeting in 2 minutes!" - "he's sending mandela down the river, he should be out in a minute"

Stand up at the sit down

When you have to use the regular (sit down) toilet to take a piss in a public restroom because all of the urinals are being used.

Wayne: All of the urinals were occupied so I had to do a stand up at the sit down.

When the sun goes down

A song by the arctic monkeys showing that all the pedofiles come out at night

“Cause they say it changes when the sun goes down, over the river going out of town.”

Heads down, butts up!

A cute and charming phrase finished by..."that's the way we like to fuck!" Of indeterminate origin and little utility.

When viewing a passed-out chick at a frat party with her face burried in the couch:

"Heads down, butts up! That's the way we like to fuck!"
