A culmination of 5+ people's shit in a small toiler that has not been flushed, resulting in extreme blockage. The manual process of unblocking the toilet with the use of a soup ladle, creating a casserole-esque substance and a heightened smell of extreme sewage poo.
Best served cold and fermented. A Dutch speciality.
