Its mostly just the dudes who believe "women belong in the kitchen har har har" so don't let them be a label for the rest of us. Cuz thuy dum er sumting. A lot of it is really just caused by jokes taken the wrong way or just bad moods. But as a male I think the main reason is a lot of guys' pride won't let them not say something, and it's like that with other guys too. I knew this one guy who just wouldn't accept defeat and kept arguing through the entire match.
