Turdtanic
When a buoyant turd starts to sink at one end causing the opposite end to rise out of the water. The turd will be unable to support its own weight and after only a few seconds it will violently break in half. The portion of the turd that was exposed to the air will come crashing down into the water and the two pieces will sink to the bottom of the toilet. Any corn or other undigested food unfortunate enough to be aboard this turd will be pulled under do to the vacuum effect the heavy turd creates as it sinks.
Dude, I just experienced my first Turdtanic. The splash got my ass all wet. I feel sorry for all that corn that was pulled under into a mirky cloud of shit never to be seen again.
