Powder Fever
Used as an excuse for ditching school/work at the last-minute to go skiing/snowboarding. Most commonly used the day after a snowstorm so that you can ski/board on some nice fresh powder.
I can't make it into work today; I've got powder fever.
I called in sick with powder fever so I could go ski some fresh tracks at Vail.
