Clean the pipe 

1. To clean a pipe in a stroking motion, in a way in which it looks like masturbating.

2. To be jerked off

Hey Brad, Sally's talent is to clean the pipe. I found out last night. That's sick bro!

To jerk off, especially prior to a date, so you aren't thinking about sex all the time.

Make sure you clean the pipes before going out tonight, so you won't have the baby batter in the brain anymore.

clean the pipes 

masturbation to prevent the pipes from clogging, which can lead to the back up of sperm that flows directly to the brain causing awkward sexual advances, undue violence, and masturbation in creative and sometimes inappropriate places.

I should clean the pipes before that date tonight.

For sure! You don't want to be going for the kiss before the bread even gets there.

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.
