Premise: A Quick Fuck is a layered shooter made from one part coffee liqueur like Kahlua, one part cold Midori liqueur and one part Baileys Irish Cream. The Baileys is poured off the back of a bar spoon so it "floats" on top of the Kahlua in a shot glass. Then slowly layer the Midori on top of the Baileys. Note that Baileys does not have to be used; any type of Irish Cream will do.
Hypothesis: The beverage is dark in color
