A cocktail made of Guinness Stout, Irish Whiskey, and Bailey's Irish Cream.
The key to the Irish Car Bomb is to drink it very quickly before the Bailey's reacts with the acidity of the stout, causing it to curdle (essentially turning it into cheese). The result makes the cocktail very unpleasant to finish.
Start out with a glass of Guinness, or Guinness mixed with a shot of whiskey. Then paying close attention to time lapsed, drop a shot glass full of Irish Cream, or Whiskey and Irish Cream into the glass. Chug.
The Irish Car Bomb is very filling and is recommended to consume it early during a night of drinking, as opposed to late.
I love turning drinking into a sport, so I ordered an Irish Car Bomb.
