1/2 oz of coffee liqueur
1/2 oz of Irish cream
1/2 oz of grand marnier orange liqueur (or orange liqueur)
1 dash of Bacardi 151 rum (or overproof rum)
First pour the coffee liqueur into the shot glass; next, slowly pour in the Irish cream over the back of a spoon and allow it to settle on top of the coffee liqueur; finally, (again slowly) pour the Grand Marnier over the back of a spoon into the glass. Add the dash of 151, light it with a match, and while the shot is still flaming, quickly place a straw to the bottom of the glass and drink quickly.
