(adjective) Normally used to describe the snow or weather conditions on a ski mountain when they become stormy, windy, icy, extremely cold or otherwise particularly difficult. Used by snowboarders and some skiiers. Linguists studying the term have concluded that it likely originated in the Sierra Nevada Mountain Range ski towns during late 2007 towards the end of the Hummer H2 age and was primarily used by resort industry instructors at June Mountain, California.
