When you have to poop in public but the toilet seat is beyond filthy so you have to crap so bad you resort to hovering above the seat in a "crumping" position. This usually results in splashing of water on the anus and/or left over fecal matter between the cheeks.
Yo Mike, I had to take a poo at work but someone pissed all over the seat so I had to do a dump n crump.
