Chunder Challenge

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.
