What is a nerd?

What is a nerd?

Lately nerds are becoming more of a compliment than an insult, and from observing some people and the internet of course, I realized that people are misinterpreting the difference between a nerd and a geek. The word nerd is becoming self proclaimed these days even they though are not nerds, now the question here is " what is a nerd?" , to answer that we have to learn what it is based on ( although there are different perspectives) like is it based on their hobbies? Their clothing? Their thinking? Their social status?  IQ? Since this word has become pretty much common, it already has a lot of definitions... so just comment if you have any ideas on this brief article. Because in my opinion Nerds are actually based on how they spend their time which is hobbies but in a more specific details like for example, I am a nerd, I like video games… but that’s not enough you have to ask like “alone? Or with people?, see there are so many bases on what it could mean that people are changing it, ( like the word “beliebers”, but we’ll discuss that  another topic), that the world nerd is actually turning to be cool, that even people who are not “nerds” are calling themselves nerds, which I think is pretty pathetic of them just to fit in a crowd… thoughts?
