The Orgasm is a cocktail that can be either served on the rocks or layered and drunk as a shooter. It is an IBA official cocktail.
There are many other versions of this popular mixed drink. One of those forms is remembered by "being made on your B.A.C.K.", or made with Bailey's, Amaretto, cream (half and half) and Kahlúa, with each ingredient having a one part measure. Another variation contains Vodka, Amaretto, Triple Sec, White Creme de Cacao, and Light Cream. The light cream has a 1 oz. contribution to this drink while the other ingredients have a 1/2 oz. contribution. This variation of the recipe is more commonly known as a "Screaming Orgasm". Cocktail recipes change over time with the addition and/or subtraction of their ingredients.
