I heard a quote today on the radio from Dr. Michael Fine, Rhode Island's director of the Department of Health, where he used the phrase "scathingly small" (e.g. here) when referring to Ebola's chances of occurring in RI:
“The likelihood of anyone in Rhode Island having or getting Ebola is scathingly small.”
That phrase -- scathingly small -- caught my attention because it didn't sound valid. I searched around and couldn't find any definition of "scathing" or "scathingly" that would seem to lend itself to that context. In fact, when you Google "scathingly small" (with quotes), the only links that come up are in reference to Dr. Fine's statement. I know that could be Google's search engine optimization at play, but still...
Is that a valid use of the phrase, and, if so, what is its definition in that context?
