"Man the fuck up"?

Since when has there been an all-accompasing definition of what a "man" is.

Am I any less of a man because I paint my nails, occasionally put on eye-liner when I go out, moisturise and use expensive hair products; all because I like the way it looks? Or, in reality, am I more of a man because I have the balls to be self-expressive in a way that I feel reflects my nature and not give a shit about what anyone else has to say about it?
