It was invented by Sarah Palin, the Bard of Wasilla, who joins William Shakespeare, Stephen Colbert, and Twitter in adding to our modern lexicon.

Based upon Ms. Palin’s single usage of the term (in a Twitter tweet, which was later deleted — why?), “Ground Zero Mosque supporters: doesn’t it stab you in the heart, as it does ours throughout the heartland? Peaceful Muslims, pls refudiate,” it seems to be a sort-of amalgamation of the words repudiate and refute — or Ms. Palin meant to use either refute or repudiate and got them confused, or made a typo (though the F key is nowhere near the P key on a standard QWERTY keyboard), or meant both but was limited to 140 characters.

Only the Bard of Wasilla knows for sure…

So, let’s work this — ’cause I think it’s fun.
