When taking a shit, and you squeeze out one hard, solid turd, but everything behind it is explosive diarrhea. The solid turd represents the cork of a champagne bottle, and the explosive diarrhea represents the champagne that explodes from the bottle like a star going supernova.

The trifecta is when this occurs while you are in an airplane lavatory, the "Champagne supernova in the sky"
ME: I thought I was going to have a normal, solid shit, but after that first turd, my ass exploded with the hershey squirts.
Friend: Whoah! That is a champagne supernova!
