When you double flush a toilet just to be courteous. Not necessarily a double-flusher, just to be polite.
Mostly used in awkward situations.
Matt was meeting his girlfriend Sarah's parents for the first time. They were enjoying a lovely meal when Matt had to take a dump.
This being the first time he had dumped in Mr. And Mrs. Di Carlo he flushed twice even though one should have been enough.
Matt demonstrated the courtesy flush.
