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.

Cleaning out his pipes 

-a more sophisticated way of saying "sucking him dry". Basically, men are continually producing semen, and after several days the urge to cum becomes unbearable. So his gf/wife makes him ejaculate via fellatio/intercourse (the ejaculation is often both powerful and plentiful), then blows him for several more minutes, sucking out the rest of his love juice and swallowing it. The last steps are highly recommended to insure he is completely dry and empty.

-"Pipes" refer to the long, twisting canals of the interior male genitalia.

Daniel had gone to the East Coast to visit grad schools and did not get a chance to masturbate even ONCE during the trip. When he got back to Berkeley, Jamie, his fiancee, sensed he needed to shoot badly so she sat him down and immediately got to work cleaning out his pipes.

Cleaning the Pipes 

When you go into the bathroom and you end up taking a shit, pissing, and ending with a good ol' hearty fap.

"What the hell is he doing? He's been in the bathroom for 40 minutes."
"Prolly just cleaning the pipes"
