I think this is a common tactic, especially for children and stereotypical nerds. I remember in elementary school justifying being bullied everyday by imagining how much smarter I was than everyone else. As a teen I joined a variety of counter cultures and I only listened to obscure music because I looked down on anything popular. It was only later that I realized this was just another version of viewing things as "common" and so I forced myself to get over my elitist attitude.
"Aloof" might be the image you are describing, which is a bit nicer than arrogant, but still maybe not the one that will make you the happiest. I tried "bored and indifferent" for a while and people seemed to respond well to that. Currently I'm attempting to simply be myself, but talk less around those that will think I'm weird, but it's hard for me since I apparently have no filter at all.
One thing I found was that appearance trumps social skills, at least for females. If I looked good it really didn't matter what I said, people would actually seem to be making an effort to impress me. It was really weird. I think dressing well and looking confident would work well for a man as well though. People tend to view attractive people as superior, which is silly, but it does lower the social expectations.
The other thing that helped me was to make a check list of things to say and rules for social interactions. I would then do my best to apply these, and it made me a little less awkward. Most people like to talk about themselves, so if you can encourage that, they'll remember you positively. They also tend to like it when people are pleased to see them, but not pushy, because most people are insecure but have just learned not to show it. At least that's what I understand from reading books on how to talk to people, lol.
Of course, if you don't want to socialize and just wish to remain detached, there's nothing wrong with that at all.
