ghost deuce

When one takes a dump in the toilet but it is nowhere to be seen, also when wiping there is nothing there

Dude! I took a shit yesterday and there was nothing there!

That's what you call a ghost deuce my man.

I took the biggest ghost deuce the other day. I couldn't believe how clean that toilet was after I was done.

Ghost the deuce

The act of taking a poo, then leaving without any acknowledgment of its existence including wiping, flushing or saying goodbye.

What's that smell? Did you just Ghost the deuce??
