What is the origin of ‘Take a powder.’?
Does it have to do with women applying make-up? That is, ‘Let’s excuse ourselves from this situation. We’ll be right back.’? Or is it, ‘Oh, go powder your nose, you girl!’ or ‘Will you please excuse us? Perhaps you can go powder your nose.’?
Or does it have to do with taking powdered medicine? (Though that doesn’t make as much sense to me as the make-up origin.)
