A term used to describe the white blindness experienced by a skier when making epic turns in deep, fresh, light powder. The skier's vision is completely obscured from snow kicked up by the skis, appearing as if he were inside a white room.

When riding deep powder and you stop, turn, or do anything to cause the powder to engulf you, as if you are in a room of snow. The whiteroom also cuts off your vision when inside it, it is like being in a cloud.
