To get conned by an Irishman.

When your wife or girlfriend gives you a hand job on St. Patrick’s Day.

Ireland.

(n) A hickey

When, as the girl of the night is sucking your cock, you proceed to pop open a can of Guinness and, after taking a drag of its deliciousness, you pour it on her face, taking extreme pleasure in her agony at having snorted Guinness... All on St. Patricks day...

The luckiest but smallest weenee in the world, except for the Chinese weenee.

In the month of March when you go to McDonald’s if you want to add chocolate to your mint shake ask for a Dirty Leprechaun.
