Irish Blumkin 

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.

Irish Blumpkin 

A blumpkin that ends with the giver vomiting on the recipient.

The stench of Mike's shit was so bad that the blumpkin I was trying to give him ended up being... an Irish Blumpkin.
