Duck Fart is a delicious shooter made from equal parts Crown Royal, Bailey's Irish Creme and Kahlua. To me it has a chocolate milk-like taste.

I have tried substituting different brands and it doesn't taste the same. The brand of whiskey influences the taste so much that switching the brand usually changes the name of the drink.

This drink is often layered in the following order: Kahlua, Bailey's and Crown on top; but I usually just stir mine and it tastes great.
