The syndrome of being disabled in one had by coffee.
It is early in the morning. You may be on a river trip you may not. Coffeehand can happen anywhere. However this syndrome is most common on a river trip, in the morning, while you are trying to rig a boat, or do any task with coffee in your hand. You can't set the cup down or you can't drink the coffee. You are rendered disabled, by coffee; you are left with only one free hand.
