Shitism is a political and economic theory where you make money by taking shit's everyday inside a toilet, were the shit inside goes into the sewers, scans the shit to see if its actual shit or not by testing it with some automatic machine DNA cum shit 2.0 thing, then takes that shit, turns into real money and turns into a $10 dollar bill and sends it right up the toilet where the hole is. The money you make from the shit only goes to you and nobody else unless if you decide if you want to share the $10 dollar bill. -Shabaan
