3 parts Frozen orangejuice concentrate
1 part Orange sherbet (you can do without this)
2-3 parts vodka (cheap stuff works, but if your roomate's been pissing you off, steal his absolut mandrin)
mix WELL. thats the most important bit. use a blender if possible. if you let it sit awhile, give it a stir.
came up with it when I was too drunk to mix the OJ with water for scrwedrivers, and DAMN it was good.
When in doubt, one B pump off
