From my experience, when you ninja loot you are taking items off a body that cannot be given to anyone else, and your group didn't want you to, or taking them and not sharing if somene else "needs."
And on the topic of computer nerds, who cares. I can be one at times, shoot, I knew all of that besides 29. I'm exposed to crap that makes me as a teenager looks worse, i.e. tramp stamps, disrespectful kids, all that. When it all comes down to it, I don't care. If people aren't willing to give me the time and figure out who I am on their own, they can bite me. If you think I'm a loser, then go ahead and think it, but it just goes to show how idiotic you can be, generalizing.
There's good and bad in everything, don't associate everyone with the bad.
