fard

pronunciation:  I would tell you it's like saying "fart" while burying each forefinger in its corresponding nostril.  That's so gauche, though, so let's just say it's pronounced like "fart" with a "d."

Definition:  to apply cosmetics to one's face.

This is a great "f" word to use when you need a quick exit:  "Excuse me, as much as I enjoy listening to you go on about yourself, I must visit the ladies room to fard."  Or, when you're tired of explaining to friends why you're perpetually late:   "Well, you know Mary - it takes her two hours in the can just to fard."
