I had this for the first time on my 21st birthday. A group of odd but very nIce people invited me to come home with then and drink me silly since I was alone and depressed on my 21st. This is what I drank most of the night. I ended up sleeping in my car in their driveway that night since I couldn’t safely drive Float one shot of Irish Cream (NOT Baileys) on top of one shot of Kahlúa® in a double Shot Glass. Drink. Beware – these sneak up on you.
