The act of urinating inside of a man or woman's anus shortly after completion of anal sex. It is so named because a #1 is taken on top of a #2 and the resulting mess is extremely smelly and sticky. As this is one of the most horrible things one human being can do to an other it is almost always accompanied with a subsequent break up.
the highest level of horrible barbarism in a workplace or social environment. Derived from a workplace situation where the overnight crews pooped in the Ladiesbathroom sinks.
i can't believe we got stuck working at this sinkpoop place. The support people were scooping mashed potatoes with their bare hands.
