There are plenty of holiday drinks. Here is one I threw together a few years ago. As I am not aware of anyone else making one I am claiming it as a Mr. Mai Tai original.

6 oz. Yoo-Hoo
1 oz. Kahlua
1/2 oz. Creme de Menthe

Pour all of the ingredients over ice in a mixer. Give it a good shake. Strain and pour. It gives you a minty chocolaty good drink. A perfect after dinner drink perfect for the holiday season.  If you need to kick it up the alcohol you can add some vodka to the list of ingredients.  You can add between an half ounce to an ounce without changing the taste of the drink.
