If you want a drink that fucks you up QUICK, and tastes pretty good, then try this.
Put some ice in a smaller glass (around 3 inches wide and 4-5 inches tall, the smaller 'cups' at bars). Pour in some 151 (not too much), Malibu pineapple, a little pineapple juice, and a fair amount of grenedine(sp?), then top with a cherry if you feel like it. After the first one, the rest taste just like amazing juice. Expensive drink at a bar (I've gotten them anywhere from $5-$15 depending on location) but at a party or at home, a bottle of each of those things will last a while.
