Shartonnay
A derivative of the term "shart", which is the combination of a fart and diarrhea that occurs simultaneously. To make Shartonnay, you must shart into someone's drink, preferably Chardonnay, thus creating "Shartonnay".
My friend was drinking a glass of Chardonnay and when he went to the bathroom, I sharted in his drink. When he returned, it was Shartonnay.
Brewing a Shartonnay
The prelude to a shart. The brewing feeling in your stomach before sharting.
Before the 100 meter sprint I was definitely brewing a shartonnay. Right as I crossed the finish line I popped the cork and sharted all over my legs and shoes. I need to do some laundry.
