As far as beer, it's usually between Corona with lime, Bud Select 55, or Yuengling.
When I'm looking to just get messed up in a hurry, it's straight shots of Everclear. Of course, they don't sell it here in NC anymore, or at least the 190-proof version. Somebody told me they're selling something here now that's called Everclear, but it's a watered-down 160-proof something. A good mixed drink with Everclear is "Sweet Tart". You take a 2-liter of orange soda, drink or pour out half of it, put in 2 or 3 packets of different flavors of Kool-Aid (I stick to the basics when I make it- grape, cherry, lemon, etc.), some sugar (I think it's supposed to be a cup of sugar, but I don't remember), and fill the rest of the 2-liter with everclear (or don't fill it all the way up, depending on how sober you want to stay). If you mix it right, it tastes great and you can barely taste the Everclear at all. If you get it wrong, you end up with something that looks and tastes like Robitussin, lol.
I recently tried Absinthe, and that's one thing I won't be doing again anytime soon. I've been drinking Everclear since I was in highschool, and NEVER have I ever thrown up or passed out from drinking, but that Absinthe had me throwing up that night and the next morning. Granted, I'd drank alot of it and Vodka on an empty stomach that night, but that licorice taste coming back up is enough to make you not want to touch that stuff again for a while, lol.
