#1. To take a crap so big that your pants fit better.
#2. To crap a turd so big, one end is sticking out of the water.
#3. To crap so big around you have to break it up with the plunger and flush twice.
#4. When you take a crap that stinks so bad, you give a courtesy flush half way though. This act cuts down on the room aroma.
Hey Dude, I shit a Double Flusher so big, I heard my butt cheeks slap togetherwhen the pointed end came out.
From 19th c. poker players - someone who is claiming to have a five card flush, when actuality they only have four cards. NOT someone who is so full of shit that you need four flushes to send them down the toilet.
In the movie "The Great Waldo Pepper" Robert Redford's character was exposed as a "Four Flusher" for claiming to have fought a German WWI ace, when he actually had not.
