I've noticed it primarily in SF and Seattle. I've seen it to a limited extent in Philadelphia, but it's been my observation that most tech jobs on the East Coast have sufficiently strict dress codes to make lifestyles/hobbies relatively non-apparent at first glance. (the limited extent that I witnessed it in Philadelphia was at a startup that I interviewed with. One of my "geek" friends warned me that the startup was filled with "brogrammers"). Although the term "brogrammer" was not invented yet, I also witnessed it in university on the East Coast, where CS kids in fraternities were frequently given a hard time by other CS students. It definitely is "geeks" doing most of the name calling, though the twitter/SJW sphere has certainly adopted and perpetuated it as well.
