Get the power dumpmug. you know when you have to take a huge dump that youve held in for hours and then you take a poop and and it comes out like rapid fire and gets you wet. usually followed by a wet bumbum or ballsac and a really good feeling like the weight of the world has been lifted of your shoulders.
