I've even seen places in the USA where everything soda is called coke.
In that case, how would you order the drink that's actually named coke?
"Can I have a coke please?"
"Sure, what kind would you like?"
Well, that and the fact that most people actually want Coca-cola anyways.
As for the nerd thing, I've never really found two distinct areas/groups who agree on a single definition. In high school, my group of friends played Magic the Gathering (and other card games), watched anime, read manga, and in general much of our sub-culture was based on internet culture, such as L337 jokes, AYB, and homestarrunner. We called ourselves nerds willingly, and we didn't take any offense to it. We also considered ourselves to be partly geeks, but not completely. I think it's best to say that we borrowed things from what we considered geek culture. That would have been the leet, AYB, linux, and stuff like that. But in general we still considered geek to be a bit of an insult. I guess in our minds, it had to do with the antisocial aspect. Nerds like us had a huge group of friends (actually we were probably the largest social group in the school, since we drew in members of other groups too), while geeks were more of loners. We actually had a joke between us that, after being called a geek, we would say something like, "Hey! I'm not a geek! I'm a nerd. Get it right." Like I said, I'm not really sure why, it just seems like it happened like that.
I don't exactly think of it the same way any more, but I still have the instinct that geeks are more loners than nerds.
