Unpooptankable Edit Meaning

1.

A toilet, such as the models found at most Starbucks coffee shops, which features a pressurized water resivoir. Such toilets are not condusive to the art of the poop-tank, as the poop merely lies inside of the porcelain tank instead of undergoing the magical normal water to 'dump water' transformation. There are no known poop-tank methods for toilets of this type at this time.

It became evident the instant that I removed the porcelain lid of the toilet within Longs Drugs that the execution of a poop-tank would be impossible; the pressurized water system had foiled me again! Curses!
