Irish Cuisine is what you call delivering a hot pile of liquified feces onto your lovers chest during intercourse. It gets its name thanks to the description Denis Leary gives for traditional Irish food being boiled in a pot for 17.5 hours.
"I served up some Irish Cuisine for my girlfriend last night."
"Oh yeah? How'd she like the corned beef and cabbage?"
"No I wouldn't give her that - I had diarrhea and shit on her chest after I fucked her."
