1.
A childhood game where kids climb a pile of snow and try to be the only person standing on top. Kids push each other down the snow pile and tries to get to the top to push the "King" off so they can be the new king.. until someone pushes them off. Quite dangerous. Many injuries may occur, depending on icyness of snow pile and violence level of children participating.
"Krista, come outside, hurry! The neighborhood kids are playing King of the Mountain!"
