Clean the pipes 

Urination by a man following an act of masturbation or sex. Presumably any semen left in the tip of the penis will be cleaned out by the pressurized urine stream.

After I busted on Mary's face, I went to the bathroom to clean the pipes before I kicked her to curb.

Polynesian Piledriver

To have anal sex with a stack of pineapple rings positioned over the anus while the person is upside down with their ass in the air.

Sally is a real go getter, she'll do anything, last night I introduced her to the polynesian piledriver

Piper

To be in a super duper fantastic mood. To have a strange curiosity that makes you addicted to the site of monkeys.

I was in a real piper mood today, we got to see a live monkey in Zoology!
I was really piper about the new girl down the street.

Alaskan pipeline 

When a girl takes a shit inside of a condom, freezes it, and uses it as a dildo.

I made myself a great Alaskan pipeline last night.

vein laden meat pipe 

A large completley erect penis with veins protruding from the sides of the swollen penial shaft.

She licked and gently stroked his cock for so long, it had become completely engourged, a "Vein Laden Meat Pipe" ready to penetrate into her soft, wet, gasping pussy.
