Reverse Tehuacán Cuba Libre

After a night of drinking Bacardi, bowel movements are so distressed that poop comes out in a machine gun likeness.

In this scenario, the famous waterboarding with sparkling water technique of Federal Mexican Police Officers is done in reverse, to mean that it's done in the ass.

I felt like a Mexican Pollock after bending over and doing a Reverse Tehuacán Cuba Libre.
