Dump n crump 

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.

crump 'n' dump 

The dance you perform when you think you have bought into the bottom of the market, only to see the Dow drop below 7,000.

I was doing the crump 'n' dump when I saw the market tank right after I bought in.
