It's quite simple, really. We form the snow into ice golems, or as the heathens call them, 'snowmen', which ward off frostbite. Then we shape other pieces of it into spheres which we hurl at each other as a barbaric sort of natural selection- survival of the fittest, as they say. The winners lie in the remaining snow and wave their limbs about wildly, thus creating snow angels that cart off the dead.
