I agree that a job post for brogrammer might not seem welcoming towards woman.

>You realize that bro culture and brogramming are actual, existing things started by guys, yes?

Please tell us your definition of brogramming and brogrammer.

From watching the initial joke video on brogramers I understood that brogrammer is a prejudice term for male coder which likes to party, drink alcohol, flirting and is usually more interested in main stream culture. There is nothing wrong with any of those qualities but we still talk about brogrammers as bad people. Aren't we also sexist and prejudice?

What would you say about an equivalent sisgrammer term for woman?

I would say that you seem to have a poor understanding of pop culture in the US. Bro culture is a prexisting thing. See, e.g.: http://www.mediaed.org/cgi-bin/commerce.cgi?preadd=action...
