five o'clock shadow
A light regrowth of facial hair, at or as at the end of the day after one has shaved in the morning. No, you look very distinguished with that five o'clock shadow. I've got another meeting this evening, so I need to go get rid of my five o'clock shadow. I'm not a big fan of facial hair, but a five o'clock shadow is OK.
