NO MIXING ALLOWED!
Layer each drink in over a spoon starting with the Kaluha, then Galliano, then Blue Curacao then Chartruce (preferrably Yellow — but green will do) on top. Serve in a martini glass with the Chartruce set on fire.
Shove a straw in and drink from the bottom (before the straw melts dammit!).
Yum and yum. You will be DRUNK.
