The act of going to a theme park of sorts, locating the pizza hut and getting the buffet lunch - attempting to eat as much pizza as possible, no salad allowed. You then, immediatly after consumption of said pizza, ride the largest/scariest rollercoaster in the park. Attempt not to coat everyone within 10 meters with mushrooms, pepperoni and pepsi.

The NFC originated in Flordia and is rarely attempted by normal people. The challenge is to not flush the toilet for as long as you can while withstanding the putrid smell and horror that will eventually build up inside the bowl.
