Rasberry flavored vodka and cranberry juice can be mixed at a very high ratio and still taste good. usually a good favorite of women, although it does taste good.
also, rasberry vodka and some sort of orange liquer (like cintronaeu or whatever it is, or even cheaper -- blue caraceau) can be mixed and it tastes ok. if you add some club soda or sprite to it, it might add a little something. looks like toilet bowl cleaner, but whatever.
basically, the more sugar you add to a drink, the better it tastes if you don't enjoy the alcohol taste. (maybe why the sprite added to the taste)
but carbonation will increase the absorbtion rate so you might need to pace yourself more....
also you can f-- around with jello mix and grain alcohol and make some punch. only problem is that the crap can stain the hell out of anyhting, and its wicked sweet which might be a problem for the male counterparts of your party. but if you need a really high alcohol content in a small amount you can go with that.
I assume you're trying to go somewhere like a concert or similar and take limited quantities that should "get the job done". consider buying liters of bottled water and heating the caps until they come off without breaking the plastic seal. you can replace the water with captain morgan's silver (clear spiced rum) and any other clear mixer. get the cap back on when its warm and it will re-cool and you can't tell it's been tampered with. buy sparkling water bottles if you're gonna replace it with sprite or club soda as a mixture..... it's a great combo around here for the jimmy buffet or other concerts that only allow you to bring in bottled water.
