I enjoy long meandering discussions with a few people who either know what they're talking about, or are at least interested in listening to someone who does. I have a few areas that I consider myself quite knowledgeable in, and I'll gladly talk your ear off if you'll let me, or I'd just as happily listen to your areas of expertise. This can be greatly enhanced by a few beers or glasses of wine, and maybe a card came or movie to talk over.
Internet: Reddit, xkcd, wikipedia, kqed, youtube
Movies: Chicago, Boondock Saints, Matrix, Star Wars, Documentaries, "Sword and Sandal" epics, sometimes those obnoxiously hip little indie movies, Kill Bill (a lot of Tarantino I guess) lots of other stuff too.
Shows: The Office, Parks and Rec, Always Sunny, Game of Thrones, Breaking Bad, QI, sometimes Glee, Raising Hope, etc.
Music: Punk rock, classic rock, show tunes, Johnny Cash, Celtic music, folksy. My taste has been described as "dad music", which sounds about right.
Food: I'll eat just about anything, and usually love it. Burritos, Chinese and burgers make a lot of my diet these days, interspersed with whatever stir-fry or noodles I feel like whipping up.
At this point I will start rambling the sort of thing that passes through my head.
I sometimes find the most useful description of someone's position is the offensively exaggerated/oversimplified one, used by their critics such as those commie homo hippies or them gun totin' bible thumpers. My favorite of these is "The Blandest Propagandist" (NPR). I also often find these terms amusing.
I've also leaped to the conclusion that the difference between decent pizza and great pizza is a lot more garlic.
I sometimes like to ponder the distinction between very similar words, like jealousy and envy. One can be jealous of their significant other, or their possessions, in that they do not wish to lose them, as a dragon jealously guards its treasure. One can be envious, on the other hand, of someone else having a more attractive significant other, or bank account, etc. That being said, I think that jealousy is a trait that gets a worse reputation than it deserves. There's the down side that jealousy can imply a certain amount of mistrust of one's partner, or feeling possessive, but it also comes from very strong feelings for them. I feel like I'm rambling away from anything like a point there, so I'll stop that now.
