Houdini shit 

The actual definition of a Houdini shit is a turd that contains enough negative buoyancy to drop to the bottom of the toilet and glide it's way down far enough into the toilet's exit portal that it appears to have mysteriously disappeared or make you question whether or not you even crapped to begin with. It often times shares the characteristics of a Jesus Shit, which is the term used for turds that leave no residue on the anus.

Boy, today's Ziggy cartoon was pretty funny. Oh well...I'm done wiping so I guess it's time to stand up, flush and get back to wor- OH MY GOD! HOUDINI SHIT!

The act of taking a shit, and not having to wipe due to the turd not leaving a mess on the outside of your asshole.

Houdini Shit

When you shit so smoothly that the turd(s) carry enough momentum to go up and over the bend in the exit pipe of the porcelain throne, disappearing the evidence of your crimes.

One half of the double-miracle Jesus Shit.

I couldn't believe my eyes! I must have Houdini shit (shat), because when I looked between my legs, there was NOTHING in the bowl. I looked behind the toilet... nothing!
