An Irish Car Bomb is a popular American bomb shot cocktail, similar to a boilermaker, made by dropping a shot of Irish cream and whiskey into a glass of stout. Its a medium strength drink and is fairly easy to make. The "Irish" in the name refers to the drink's Irish ingredients; typically Guinness stout, Baileys Irish Cream, and Powers Irish Whiskey. The term "car bomb" combines reference to its "bomb shot" style as well as the noted car bombings of Northern Ireland's Troubles.
