Here is a song called “Masculine Women and Feminine Men” released in 1926.
Masculine women, Feminine men
Which is the rooster, which is the hen?
It’s hard to tell ’em apart today! And, say!
Sister is busy learning to shave,
Brother just loves his permanent wave,
It’s hard to tell ’em apart today! Hey, hey!
Girls were girls and boys were boys, when I was a tot,
Now we don’t know who is who, or even what’s what!
Knickers and trousers, baggy and wide,
Nobody knows who’s walking inside,
Those masculine women and feminine men
