root beer float 

upon finishing the activity of an "upper decker" (shitting in the upper tank of someones toilet) you then dump an entire bottle of dishwashing soap in the tank and then flush the tiolet so the bowl fills up with bubbling shit water....

Tom pulled an upper decker on Bills shitter, and I finished it off making it a root beer float!
