Lets see...an old friend of mine used to drink Malibu, coke and orange juice. It looked something you'd find in a sewer but tasted awesome.
The other was a "punch" I drank at a party once, which consisted of Vodka, Tequilla, Sambucca, Jack Daniels, White Wine, Red Wine, Bacardi and 2 or 3 cartons of Orange Juice/Cranberry Juice. You couldn't taste the alcohol but half an hour later...it hit you. I must have drank far too much because the next night I'm sitting at home feeling like shit, shaking like a leaf.
