Question: Can the phrase right-hand man apply to a woman? Or what would you say? Right-hand woman? 

Answer: If I were the right-hand, I think I'd rather still be called right-hand man. Right hand woman just sounds lame, like we're trying to be sensitive for difference, and I don't really care, except for the words that are "esses" like actresses. That one's important.
