Any Nerds/Geeks?

What is a nerd and what is a geek? Are they the same thing? Is it just someone with no social skills?

Ask modern society

I'm curious how self-defined geeks and nerds see themselves.

I mean I quite like star trek and physics and stuff but I would never describe myself as a geek because to my mind it conjures up the socially awkward characters of the big bang theory.

Hardly. the characters you see in shows like the Big Bang Theory are just characters. Really just stereotypical representations of what society thinks "nerds/geeks" are

Those who commonly refer to themselves as nerds/geeks do so because of a great interest in a particular thing or number of things. For instance, many people call themselves nerds because they really enjoy A Song of Ice and Fire (Game of Thrones)

It takes a few visits to large cons like MCM to realise that most people under this self proclaimed moniker are just ordinary people with extraordinary passion for something

I like Game of Thrones, I still wouldn't say it makes me a geek.

So you think the definition of a geek is someone with a great interest (ie obsession) with one particular thing?

Can the obsession be with anything? or just specific types of things? Like if someone was obsessed with american football or casual sex, would he be a geek?
