Verb used loosely to mean "reject": she called on them to refudiate the proposal to build a mosque. [Origin--blend of refute and repudiate].
According to the OUP Blog, "the word refudiate instantly evokes the name of Sarah Palin, who tweeted her way into a flurry of media activity when she used the word in certain statements posted on Twitter. . . . [W]e have concluded that neither refute nor repudiate seems consistently precise, and that refudiate more or less stands on its own, suggesting a general sense of 'reject.'"
