What’s the word for…

NPR ran a fun story the other day about coming up with words to express feelings or situations that we don’t have a word for.

My question is: what’s the word for the fear of writing “Love, ” (Like you would maybe automatically do to your spouse) at the end of an e-mail to your boss?

I’m not the only one who’s worried about this–a few weeks ago a coworker expressed the same fear.
