Mainstream culture is like your mom: It's always a little late to catch on and gets easily confused by technology, but it means well.
My mom is a big sports fans. Basketball, football, baseball, whatever. She calls into sports radio shows and gets into shouting matches, that's how intense she is about it.
I feel like being nerd is not about the superficial quality; it's about how nerds approach life. It's much more emotional and mental than it is you're some fat guy living in your mom's basement, which I think is just a hacky stereotype.
