When a male masturbates and puts his thumb over his bell-end just as he ejaculates to get a pressure build up in his urethra that can then be sprayed just like champagne out a bottle.

When a person shakes up a bottle of champagne, puts their thumb over the top and then shoves it into the anus of another person. After a moment, that same person then drinks the explosive diarrhea-champagne mixture that explodes out of that person's ass like a water fountain.
Oh man, she bent over and let me champagne supernova her ass. I can still taste it.
