When a man spend all day eating corned beef and cabbage, and drinking green beer on St. Patrick's Day. While he's sitting on the toilet taking a stinky shit and a lady comes in (wearing a red wig and tartan skirt preferably), and gives him a blowjob.
Dude, Joan was so drunk on St. Paddy's Day she gave Bill an Irish Blumkin at the Shamrock bar.
