I wanted to share this with people because I'm a fan of obscure/outdated terms.
I recently came across the phrase "Incorrigible Quidnuncs" in a work by Robert Frost.
(Sorry, I didn't note which one; I'll note it later if I remember)
I was intrigued by the phrase because I had no idea what a Quidnunc was, much less how it could be incorrigible.
I found this definition at dictionary.com:
a person who is eager to know the latest news and gossip; a gossip or busybody.
Thus, an incorrigible quidnunc is an unabashed gossip, someone wholly incapable of keeping a secret or minding their own business.
I think it's a wonderful phrase and would make a great name for a gossip column blog.
