"Man Up"

I find the turn of phrase "man up"to be pretty cringeworthy, and I also find most things that come out of Angle's mouth to be cringe-inducing as well, so imagine my face when I saw this debate footage. Instances of women using this phrase introduce a whole new level of internalized sexism. If telling someone to man up is tantamount to telling them to "toughen up," are women not tough? Must men always be tough? I'm sure you all can think of many more problematic aspects to this phrase, it's use by women, and especially its use by a politician with such extreme anti-woman views.
