It's treating a woman politely

As long as she isn't a fright:

It's guarding the girls who act rightly,

If you can be judge of what's right;

It's being—not just, but so pleasant;

It's tipping while wages are low;

It's making a beautiful present,

And failing to pay what you owe.

From Our Own Nursery Rhymes

"Chivalry, Chivalry, where have you been?"

"I've been out seeking a beautiful queen."

"Chivalry, Chivalry, what did you find?"

"Commonplace women, not much to my mind."
