I'm usually tested in the 150-160 range. What others describe is similar to how I think. I don't have trouble in social situations though, and I rarely feel lonely. I can relate to people of any intelligence level.
One thing that I didn't see mentioned was that, when talking to someone about something technical in nature (like talking to a coworker about an assigned task), I will just skip to the end of the conversation in my mind. I can see where the conversation is going, what conclusions my coworker will eventually make, how I will respond, etc. Once I have enough information about the details, I'll just skip ahead in my brain, and then I have to patiently wait for my coworkers to reach the same conclusion I have. Sometimes I finish their sentences for them, to try and speed things up. Some people find that annoying, but others learn to rely on my intelligence to dictate the entire conversation. They'll start a sentence, and I'll be answering their question before anything comes out of their mouth.
However, I don't do this in social situations. I mean, that would just ruin all the fun! When I'm social, I shut off my intellect. I don't try to predict conversations, and I just act playful :-). If I start to predict a conversation, then I will intentionally say something jolting to force the conversation in a new direction. Something emotional.
When first learning to be social, I had to actively try and not become intellectual. Now it's second nature to me. When I'm being social, I just relax. I be myself. Intellect is important for communicating abstract concepts, computer programming, math, science, etc. But when I'm acting social, I communicate on an emotional level, in which case - we are all on a level playing field. "Dumb" people still deal with family, love, passion, relationships, careers, etc - the exact same way that I do. So I talk about those subjects.
The only people I have a terrible time relating to are stupid people with poor emotional skills. But that works out well for me, because even "normal" people have a hard time dealing with someone with poor emotional skills - so I'm in the same boat as everyone else.
I look at my intellect as more of a possession than of something that defines me. It's like a cool toy. I treat it that way with my friends too... sort of just play around, and see what I can do with my intellect. Like if you bought a new car. You'd show it off, and your friends would have the reaction of, "Oh sweet dude!" But everyone knows it's just a possession. I try my hardest to ensure that no one feels intimidated by my intelligence, and always try to include everyone in a conversation - speaking to them in emotional terms. Not logic or math :-P. When my friends feel like playing with my intelligence, I play along. It's like a game though. We poke around in my brain to see what's in there, until we get bored. Then we'll do something else.
