The term Cummins can be referred to as an American living in a poor, "bad", or high crime rate area of a large German City. The area is normally run down, where drugs are very present. Rolling power outages and no hot water are common place in this area.
I know this Cummins who lives in Stuttgart, I really hope he makes some money so he can take hot showers and doesnt have to worry about the power going on and off.
Cummins is a term a select few of Americans and Europeans use to describe a person who pees or soils themselves when they drink to much. Often this is the person who pees them self during the night or while be passed out, then not claiming it was them who did it in the morning or when waking up.
