look up any word, like cunt:
the act of shitting on someone's forehead and then slapping it with your ass cheeks. similar to the cleveland steamer and the boston pancake but alot messier and for sick bastards only. make it a new york buttered flap jack by adding a squirt of jizz.
-Fozz: "Dude, what the fuck!!!?? What is this fucking joop on my head???"
-Dirty Dan: "I just gave you a new york flap jack ya dick."

-Darwin: "I'll have the new york flap jack."
-Waiter: "You sick fuck...(gunshot)"
-Jimbo: "Oooh...leave the body here, someones gettin laid tonight!"
