Butterfreeze occurs when one falls down a small mountain and sustains a leg injury, causing them to walk slowly for a few minutes.

Alternatively, Butterfreeze occurs once every 47.8 years, when a small asteroid hits the rings of Saturn, productin small amounts of fresh butter, which when let loose into the harshness of space results in instant freezing.
