the proper act of flushing one's toilet mid-way whilst taking a dump

usually a precautionary action in order to avoid clogging the toilet

especially important when plumbing is mediocre, and strictly unnecessary on aircraft lavatories

it has nothing to do with poker
after Thanksgiving most people usually forget the Gentleman's Flush and end up clogging their toilets.
