The Dirty Toilet Game is a 2-4 player bathroom humor card game where you need to collect 5 clean toilets and discard your poops. Yet, watch out! Your opponents will try to stop you with poops, problem cards, and more importantly, dirty toilets.
Such a toilet pan is also called a "squatting pan". A squat toilet may use a water seal and therefore be a flush toilet, or it can be without a water seal and therefore be a dry toilet.
