Chaim gutleizer
Chaim gutleizer is a common form of graffiti where a man shits in his hand and puts it in an airtight container. This container would then be fermented for a full week. When the time comes the man would dip his balls in the fermented shit and use it as a paintbrush. It is commonly used on the street but it can be used on walls, buses, or even an orphanage.
My dad got arrested for Chaim gutleizering on a duck.
