Noah Rothman uttered this nice malaphor on the MSNBC show, “Morning Joe”, on March 21. He was referring to Trump’s comments about McCain and Obamacare. It is a congruent conflation (two idioms mixed with the same meaning) of “sticks in (one’s) craw” and “gets under (someone’s) skin”, both referring to something that is irritating or bothersome to someone.
So what’s a craw?
A craw is the crop of a bird or insect, the transferred sense of the word to refer to a person’s gullet (Free Dictionary). Perhaps Mr. Rothman is a Frank Sinatra fan, thinking of the song “I’ve Got You Under My Skin”. A big thanks to Frank King for hearing this one!
