Well, back in the day, "nerd" meant "social misfit". Which a lot of us were (me included), because we were too busy trying to be smart to be worried about learning how to play the social game. (Paul Graham wrote an essay about this, "Why Nerds are Unpopular".) But in the real world, it turns out that social skills also matter, and I should have realized it earlier.

But these days, "nerd" means more "socially awkward but really smart", which is neutral to positive from our perspective.

"Brogrammer", on the other hand, to me at least means "male who thinks he's really smart (even if he isn't) and therefore that he can be an offensive jerk to others, especially females". It would bug me a lot if someone thought that was true of me.

Its unfortunately that is your interpretation of the word because your definition is inflammatory

By "word", I presume you mean "brogrammer".

Do you have a less inflammatory definition? (I would claim that my definition is true to the current connotation of the word, even if not the current denotation.)

I've never seen/heard a non-derogatory use of "brogrammer" -- maybe gkilmain will enlighten us with some use I'm not aware of (has it already been reclaimed by brogrammers making in-group use of the term?), but the connotations are overwhelmingly negative: http://www.urbandictionary.com/define.php?term=brogrammer

I would define brogrammer as a programmer who acts like a (stereotypical) frat-boy.

You know, living to party, acting up in boorish ways.

Yes. Remove everything after the word smart and add "(like most people in the programming profession)"

That doesn't capture what I think of when someone says "brogrammer". At the very least, I think it also denotes a strong sense of machismo, with a connotation of disrespect for others and boorishness. It's not a positive term, generally speaking.
