The angry irishman is a retaliation for the women who wrap their legs around you during ejaculation, after the two of you agreed upon the pullout method of contraception. This also works after a broken or needle punctured condom. The male, having by no choice of his own, ejaculated into the woman, proceeds to clock her in the face with a potato sack. He then grabs the nearest hard alcohol bottle (preferrably Irish whiskey), jams it in her twat and empties it to kill the sperm.
The other night Jenna tried wrapping me to get her pregnant so I foiled her plan with the old Angry Irishman!
