Originally started in Dublin, Ireland. The act of inserting greased small potatoes in your girlfriend's ass and then packing them deeper through means of anal sex. To enhance the pleasure most people perform a Dirty O'brien while drinking a Corona light or Guinness.
While incarcerated Jimmy Boy O'doul enjoyed a Dirty Obrien at the hands of officer Paddy McFudge.

Hands down, the funniest person to exist. Has an uncanny resemblance to the president of Finland. No, I didn't know they had a president either.
Conan O'Brien always makes me laugh. He could just blink and I'd probably roll on the floor laughing.
