Victorian poop pipe

The act of lying on one's stomach and imserting a pipe or hose up one's anus whilst haveing a partner straddle one's back, huffing any rectal gassees that might be expelled. If done correctly, there is no act of flatulence, rather the stink fumes waft out at a steady, gradual pace for the huffer to enjoy at their leisure. In some cases, excrement itself can suddenly launch out of the tube, covering the huffer and adjacent surfaces in a shower of stank. This is particularly a common occurrence if the person in question partakes of a diet high in fats and low in fiber. If such an incident occurs, it is customary for the huffer to exclaim 'by jove, we have struck oil, old chap!' Failure to do so is considered both bad form and bad luck.
