This is a highly alcoholic, and incredibly good recipe I made up after having something similar my twenty first birthday. It's best at parties, because you can't really buy all the ingredients, in shooters, so its expensive to make for just a few people.
These drinks are meant for 16 oz tumblers, not small glasses. I also sometimes make a pitcher, if that seems more efficient.
Throw all your liquor into a shaker, add ice, and add the juices. I never measure but here's how I prioritize the juice - use the most lemonade, second most cranberry juice, then grape juice. The lemonade and cranberry juice really make it a tart drink, as opposed to a hangover in a cup! Enjoy responsibly!
