When you take a shit and the first part of it is solid (aka the cork) but immediately afterwards the rest of it is diarrhea and comes blasting out and splatters all over the toilet bowl(just like champagne if you were to shake it up and release the cork)
I was taking a dump the other day and couldn't figure out how to describe it,It was so POWERFUL that it splattered everything in the bowl and the smell was so wretched that it had to be named. so some friends and I got together and coined the name Champagne shit

v. - A shit where a lump of constipated shit is blocking off a collection of Diarrhea shit, ergo, upon the release of the constipated shit you have "popped the cork" of the shit.

Guy2: "Oh, that was Bill, he had mexican last night so I think he's taking a champagne-shit."

"champagne shit"

-a style of shit.

It’s the shit when you sit and there's a cork of shit and you just have to push threw it in order to pop and after it pops all the shit comes out watery.
