The phenomenon that takes place when one takes a hefty dump but the feces slips straight from one's hole down the plumbing of the toilet so as to be completely hidden when one stands up to inspect their work.
"Dude I just took a massive dump but when I took out my phone to send you a pic it was another copperfield, so I sent you pic of some smegma instead."
