A champagne socialist is someone who talks about and identifies themselves as being someone on the left wing, for example a socialist or communist, but lives a life of indulgence in extremely trivial and material things.
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 dumpthe 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
