I'll be the first to admit this drink sounds wretched. Mixing it isn't an exact science either, but it makes a great party drink for a large crowd. A Tsunami should be made in a large cooler. Dump a bag of ice into the cooler. Then, add an entire case of beer. Something cheap and watered-down like Natural Light. Then, add a handle of cheap vodka. Then, two of the big containers of Country Time lemonade mix, one pink and one yellow. Add 4 cans of Sparks, one large cranberry juice and one grapefruit juice. Stir the hell out of it (the powdered lemonade will sink to the bottom). Enjoy. And watch it, it's much stronger than it tastes.
