From the response I got to the question "What is your favorite 'non-dude / non-bro' or 'douchebag-free' place to watch sports in Houston?" on Facebook, it would seem that a sans-bro sports bar is something of an oxymoron, the majority of responses falling somewhere along the lines of "in my living room" or "on my couch."
Then again, there could be some confusion about the meaning of the word "bro." Bro is not a euphemism for those with a Y chromosome, as finding a sports bar entirely devoid of men would be damn-near impossible and not nearly as enjoyable (for me, at least). The "bros" referred to in this article are defined by Urban Dictionary as:
An alpha male idiot...white, 16-25 years old, inarticulate, belligerent, talks about nothing but chicks and beer, drives a jacked up truck that's plastered with stickers, has rich dad that owns a dealership or construction business and constantly tells this to chicks at parties...identifies excessively with brand names, spends a female amount of money on clothes and obsesses over his appearance to a degree that is not socially acceptable for a heterosexual male.
