Double Kill
The act of flushing a toilet after you used it, and then unknowingly flushing it again while it is still flushing, resulting in a failed flush attempt and a hollow flush sound. However, if for waiting 9 seconds, the crap is still in there, Double kill it.
All the other men stared awkwardly at Bob when he went for a double kill in the urinal. Why would he double kill? He wasn't crapping. It was completely unnecessary.
