The New York Times (December 28) article, Words for the Dumpster begins with the following sentence:
With the last tick of 2013, let’s throw out the most annoying, overused and abused words of the year. A few of these terms, “twerking” or “stay classy,” die a natural death when someone like John McCain starts using them — the aural equivalent of a comb-over. Others need a push.
Merriam-Webster Dictionary defines “comb-over” as:
an arrangement of hair on a balding man in which hair from the side of the head is combed over the bald spot.
I understand “comb-over” also means to investigate / search for thoroughly. But neither seems to be relevant to the usage of “comb-over” in the above quote.
What does the author means by saying “A few of overused and abused words of the year die a natural death when someone like John McCain starts using them — the aural equivalent of a comb-over.”?
