There was the word “cement-mouthed” to describe Texas governor, Rick Perry in the following text of the article titled “The Republican brain drain” appearing in today’s (September 25) Washington Post.
“The list of Republicans who looked at Iowa’s daunting demographics and did not run is more distinguished than those who did. At one time or another, Michele Bachmann and Herman Cain were front-runners. Can you think of any two people less qualified for the presidency? How about Ron Paul, another front-runner, or Mad Newt Gingrich or Rick Perry, the cement-mouthed governor who would eliminate three Cabinet offices, if only he could remember them?”
I cannot find the definition of the word, “cement-mouthed” in any of English dictionaries of Cambridge, Oxford, and Merriam-Webster, nor does Google Ngram register this word.
What does “cement-mouthed” mean? Is “cement-mouthed” a neologism invented by the Washington Post Opinion writer, Richard Cohen?
Is the meaning of “cement-mouthed” automatically communicable to most of Americans?
