Out of curiousity, what or who is a SO?

For me, it's quite basic. I do what I want to whom I want when I want. I do it because they have something or can do something for me and they're basically out in the open for the picking. I rank people on a scale or hierarchy, with myself being at the very top. People can be raised or lowered on it. If I do something it's always for 1 main purpose (although can also be for some others) but the main one is this: looking out for number one, myself. I am pretty lousy at putting myself in other people's shoes but there's a simple explanation: why should I? If I'm better than they are, have more power, they should try to put themselves in my shoes.

I guess one other reason why they say I could have NPD is I'm sarcastic to people, I look down upon them, I absolutely love power and control over something/someone, try to go with those who have more power (i.e. talk to the boss, not a janitor), etc... . I think that's a fairly short and nice summary without mentioning any damage done.
