An action caused by the effect of gravity taking hold on an enormous turd falling towards the bowl water of a toilet, which allows great forces of water to splash upward on the bum.
"Does this toilet has a bidet function or was that a huge back splasher!"

When you poop and the turd creates so much force when it hits the toilet water that some toilet water splashes up your back
