Ah yes, metrosexual -- the ridiculous idea that a man might take some care in his appearance and some joy in his life.
I think the screaming was part and parcel of the outsourcing of labor from men to women, and the keen desire by many men to keep it that way.
"Looking good is HER job, but it's also her job to make sure I look good, and to tell me when that is, and also to do the dishes, laundry, raise the child, vacuum, cook, support me in all things...."
"Metrosexuals" were men doing "women's work" by being fully capable of competently handling their own styling and grooming, and by merely existing it showed men who relied on the women in their lives to nag them into clean clothes and regular haircuts were just being lazy.
And so of course the long-running joke about metrosexuals is that they were gay. Both because it was "feminine" to be able to handle that, but also because obviously only men who didn't have women in their lives would need to.
