Agreed, labels suck, though I have been called a bro-grammer and for some reason it doesn't bother me. Maybe because its the antithesis of nerd.
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.
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.)
You know, living to party, acting up in boorish ways.
