The act of squeezing your butthole closed tightly in an attempt to chop your turd in half as it exits your anus. To complete a successfull chop-flush you must flush right after your initial chop so you don't clog the shitter.
Man, the biggest turd came out of my ass the other day while at work. Good thing I did a chop-flush so I didn't clog the shitter!
