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: In A Quick Fuck you need to pour the Baileys off the back of a bar spoon to make it float on top of the Midori.
reason: The Midori is layered on top of the Baileys so it stands to reason that you could not pour the Baileys in on top of the Midori.
