1. Jacking off to dispose of excess cum (if it has been awhile since you last fucked) 2. Jacking off earlier in the day when you will be fucking a hot broad later (in order to last longer)
Since I was seeing Jessica later, I performed a Cleaning Out the Pipes!

After ejaculating once, cleaning out the pipes is when he keeps fucking or wanking hard into another, weaker but still present orgasm, which doesn't expel any semen except that which was leftover in the penis from the original orgasm. Harder for those older, easier done by those you and testosterone filled.
Cool dude: "Man last night i was with mah girl and i came once, then i cleaned out the pipes and she loved it"

Lame dude: "Yeah, I cleaned out the pipes too, but I was alone..."

Other dude: "I heard about some guy in ST. Louis cleaning out the pipes, i heard he could do it twice in a row!"

A new hazing tactic used by Frats and Sororities across the nation.

The sister sorority’s pledges take a trip to a Mexican restaurant and must eat really spicy food. Afterwards they take laxatives. Then, they go outside and play volleyball or something else for a while to get absolutely drenched in sweat and develop really bad swamp ass. This is the preparation phase.

Next, the sister pledges are made to get on their hands and knees in a doggystyle position and the brother fraternity’s pledges are made to get behind them and stick their tongues deep into the assholes of the sisters. The boys are now the pipe cleaners. The sister pledges are supposed to ride their tongues in and out of their assholes using it like a pipe cleaner. Usually this is made to last at least 10-15 minutes. During this, the girls must try to fart as many times as possible. At the end of it, the girls with the 5 fewest number of farts must then become pipe cleaners for the girls with the 5 highest number of farts. So this produces the incentive to not lose.

Rules: Under NO circumstances is a frat pledge allowed to pull his tongue out of the girl’s asshole until he is told that the time is up. He could be subject to restarting AND being made to do it 2 or 3 times if he does.

There are no restrictions on how many times a sorority pledge can fart or how aggressive they are allowed to ride the tongue of the frat pledge. While shitting is not allowed, sharting is to be expected due to the laxatives.
I heard John went though the pledge pipe cleaning yesterday. He told me he can’t get the taste out of his mouth no matter what he does!

-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.
