Now that the holiday season is in full swing, this is the time you dust off the old classics like "A Christmas Story" or "Christmas Vacation," and sit around the TV with those nearest and dearest.

But starting Friday, you'll have another movie to add to the holiday canon.

Not only hilarious, it combines a "Hangover"-style party-hard/male-bonding vibe with classic holiday movies of the past to create something that's certain to be an instant classic.
