The act of having to use the sphincter to break apart a shit, in order to make it into a size that can be managed more easily by your shitty toilet.

Can also be used to describe the act of shitting.

The act of defecation. Taking a crap. Shitting. The Deuce is the noun for the fecal matter, and to "snap it off" is to excrete it.
Come on into the theater, I got the tickets!

Okay, but you get the popcorn because I have to snap off a deuce really quick.
