I drank one yesterday. Cost me about 45? *sadface*
But yeah, bring jäger, and maybe mix it with red bull, if you're keen on seeing hyperactive underagers.
Whaat, where do you live? And mixing jager with red bull makes me cringe, cola or peach ice tea works best.
I can't believe people around the world know so little about drinks

In Slovenia, everyone basically knows what and how to drink, from the lowliest geeks, to the nasty alcoholics.
Beer always works, no matter what, wine is second best (where I come from almost every family has their small vineyard, so everyone brings a couple of liters of their homebrew wine, tastes hella good, but you can get a couple of bottles of tasty wine for very cheap. mix with cola, or drink by itself), jager, vodka, rum and whiskey. These drinks always work and that's just the top of my head. You can find the nastiest drink in your nearest store and bring that and dare people to drink it (anything made from wormwood plants-cheap, perhaps even absinthe if you have the cash). Find this: http://en.wikipedia.org/wiki/Pelinkovac and I dare you to drink it. Gets you pretty wasted though.
EDIT: If you want to get a drink for the girls or people who don't enjoy alcohol much (yourself included), get Malibu rum. It's a very sweet drink, you can barely taste the alcohol.
