Non-Holiday Winter Party Themes

What are some non-holiday themes for a party held in the winter? I know two that are really fun.

One is a “winter blues” party, with blue decorations, food, and “depressing” games, where the loser ends up being the “winner!”

The second theme is the “winter getaway” theme, where you turn your home/garage/party location into a tropical themed party. Use palm trees, tiki torches, summer drinks, and fun summertime music to help everyone “warm” their spirits during the chilly winter months.

What are some ideas you have?
