The act of washing hair, face, arms, and possibly legs (if wearing shorts) in a sink because one is dirty, but pressed for time. Usually done by college students that work (outdoors) during the day and attend class in the evenings. This act is done very quickly when a shower is not an option.
Sorry I'm late. I couldn't get off work. I even had to take a hobo-bath to get here this early!
