The females' attempt isn't even correct use of language. In this context
man means mankind/humankind. The word
man would need
a or
the in front to make the point they think they're making.
Of course you could argue without women there's no such thing as mankind, but the same is true of the males (without males, there's no such thing as humankind either), so it's moot.
As
@Norwegian Cow said, it's bollocks and never happened. It's a made-up corny bunch of words designed to garner shares/likes on Facebook.
