In pirate lingo... groggy = drink with alcohol andnon-groggy = drink with no alcohol.
If you're having a kid or teen party, fill the bottles you find with coke and/or gingerale and label them with non-groggy rum and ale labels respectively.
Print the labels on regular paper and then, glue them to the bottles or print them on full sheet label paper and then, peel and stick them to the bottles. For extra protection for the labels, cover them with clear mactac before cutting them out.
Mix together an odd variety of liquids that are safe to digest, but taste horrible (eg. coke, vinegar, tabasco sauce, pickle juice, whatever you can think of) and attach a "Drink if You Dare" label to the bottle.
At the last
pirate party
I hosted guests were betting each other as to how much and how fast they could drink these weird concoctions.
