You are all Barbarians, empowered by the spirits of the land through traditional Shamanic Alchemy from the Cocktail Mountains.
Get a lot of different bottles of spirits together, as well as a few mixers and weirder stuff. The more the merrier. Get a scrap of paper for each ingredient and write a cool barbaric verb for each Spirit and Adjective for each mixer. Use the basics, like Punch, throw Lightning Javelins, and Argue.
Each Player comes up with their own Barbarian with a cool name, maybe even a personality beyond shouting.
Starting with the person who brought the most booze, each Barbarian narrates a scene involving an obstacle that must be overcome by one of the other Barbarians. One Player then alchemically assembles a cocktail from the available drinks, then combines the cards into saying how his Barbarian defeats the obstacle. Note what was in each drink. That player now starts describing a new scene. If there's a teetotaler, they can stay as narrator.
Keep this going until the story feels finished or it's a health risk. The Barbarian who drank the largest variety of Liquids becomes the new Chieftain.
HARD MODE: Only bring a small amount of each drink.
Unfortunately the mechanics don’t allow the use of the pun ‘Beerbarians’ but there’s always next year
