I'm a computer programmer, gamer, and social dancer. I'm not going to write a novel here - I'm sure most people appreciate some terseness in these and would rather save getting to know another for actual conversation.
People find me relaxed, especially around those I'm comfortable with. I'm an introvert, but I make an effort to get out and socialize a few nights per week. My sense of humor ranges from deadpan to sarcastic melodrama, feigned cockyness, and just plain absurdity - but I usually reserve it for those I know well enough to tease.
