This really isn't that surprising to me. Game testers are the same young kids who are running around xbox games going out of their way to be as offensive as possible to everyone. It should come as no shock that they act the same way at work when work is just an extension of their regular gaming life. I'm not defending it, mind you, since Kixeye is going way too far with it, but the 'culture' he speaks of is the online gaming culture.
