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!
