Discussion Forum—A Way with Words, a fun radio show and podcast about language

Several years ago,, the topic of "diarreah of the mouth" came up. The previous host gave us a really great sounding term for it. Can you find it from the old show. I loved the term so much that I put it in my wallet for future use, after committing it to memory I threw it out. Well I believe menopause has stripped my brain of many great words and this is one of them.
Please help.
Peace,
