For starters, you’re turning the feast day of St. Patrick into a holiday for amateur drinkers. You’re also ruining perfectly good whiskey, beer, and liquor by mixing them together and chugging them like an idiot.
Worse still, it trivializes the violence and death of The Troubles by turning it into a drinking game. That’s about as respectful people in Ireland celebrating their biggest drinking day of the year by downing two flaming shots called the “the twin towers”. Don’t do it.
