I usually drink Popov, it's a really cheap brand, but it does the job. Shots of it are nasty as a motherfucker though, because, as my friend accurately described it, it tastes "like rubbing alcohol smells". Usually, mixed with something else it's awesome.
Have you guys ever mixed Fanta drinks with Vodka? That's awesome. I've mixed Strawberry Fanta with Vodka and it came out great, could barely taste the vodka, and just after a few mixed drinks you're feelin' pretty good.
Although, last time I had Popov's, I smoked weed for the first time, and they didn't seem to mix well, I wound up throwing up my spaghetti in my friend's bathroom and falling asleep in it. Nasty, I know, but I was too weak to get up out of it!
