Grissing 

Grissing is a word that refers to the act of taking the most rancid shit you've ever smelled. Often times grissing is used a form of asserting dominance on the lesser smells of the other shitters around you. This term was first used in Nazi Germany by the guards at the concentration camps. They would take large shits in front of the prisoners of the concentration camps as a way to shame them, showing them how much better the guards were fed, thus allowing them to take massive shits. They referred to this as act as "Greishen" and the term has since gone though many phases leading to the more common term "Grissing"
