I am slowly teaching myself things I find interesting (the current list includes lots of random programming languages, neural network theory, biomimitic systems, and computer security). I am a programming enthusiast, and will espouse about it at great length whenever possible, especially in the fields of game development and web programming. In my spare time I make video games, work on some FOSS projects, and sometimes do lighting, both theatrical and event stuff.
In various other eras I have been interested in marine biology (I'm SCUBA certified), robotics and embedded programming, industrial design, manufacturing processes, quantum and temporal physics (I classify myself as an armchair physicist), and probably a few dozen other random things I am forgetting right now.
Most people tell me they thought I was scary the first time they saw me.

If you want to see a lot of words on this, I wrote up a list of all the media I consume on a recurring basis and why I enjoy it or otherwise think it belongs in my brainmeats: https://coderanger.net/media/.
Playing games with friends or watching a movie. Preferably after cooking something yummy.
Roaming Wikipedia, learning about lots of things I will never need to know anything about. Also spending more time than I like to admit on Reddit.
Being a Social Justice Mage.
Also I don't drink at all. Never have. I tend to avoid all psychoactive chemicals in general. I will have caffeine sometimes, but I try to keep it to a minimum (but I don't have a problem with those that do partake of such things).
My teddy bear is probably cooler than you, deal with it.
You are capable of an intelligent discussion.
You know where your towel is.
You want someone to talk to about all things geeky.
You aren't a smoker, or intend to avoid it while around me.
You've made it to this sentence. No really, just do it.
