Palin wrote in a Facebook post earlier on Wednesday, "President Obama's shuck and jive shtick with these Benghazi lies must end." The phrase was also in the title of the post, and included in a tweet promoting it. The post accused Obama of covering up the facts on the attack on the U.S. Consulate in Libya that resulted in the death of the ambassador.

In a segment on his MSNBC show Wednesday, Matthews chided Palin, among others, for using the expression, saying it has racial connotations. 

" 'Shuck and jive' has a particular ethnic connection, not necessarily bad in all cases, it's sort of slang," he said. "It doesn't mean evil, but to throw it at the president as an ethnic shot is pretty blatant."

Palin said she laughed at Matthews's "outrageously outraged reaction," and said he has used the expression before on his show. She also cited White House press secretary Jay Carney and New York Gov. Andrew Cuomo as having used the phrase in the past. Those references were compiled in a list by the conservative Media Research Center.

"I’ve been known to use the phrase most often when chastising my daughter Piper to stop procrastinating and do her homework," Palin wrote. "As she is part Yup’ik Eskimo, I’m not sure if this term would be deemed offensive when it’s directed at her or if it would be considered benign as in the case of Chris Matthews’s use of it in reference to Rachel Maddow. Just to be careful, from now on I’ll avoid using it with Piper, and I would appreciate it if the media refrained from using words and phrases like igloo, Eskimo Pie, and 'when hell freezes over,' as they might be considered offensive by my extended Alaska Native family."
