Pan Am smile

Also known as the "Botox smile", it is the name given to a fake smile, or a smile that only uses your mouth and not your eyes. The name refers to Pan Am stewardesses, who would have to always have on a smile when around passengers, even if it was insincere.

My mother flashed her Pan Am smile at the clumsy waitress, who would not be getting a tip.
