Look it up: Twitter abuzz after Kim Jong-Un calls Trump a ‘dotard’

What Is A 'Dotard?'

North Korean leader Kim Jong-Un had Twitter users rushing to dictionaries as he revived a centuries-old insult.

Kim had some choice words for President Donald Trump during a speech on Friday, accusing him of "mentally deranged behavior," CNN reported.

But it was Kim's use of the word "dotard" that sent the Twitterverse to dictionary websites. While not generally used, the insult has been used in medieval literature from the ninth century.

Kim basically called Trump old and senile, but while Kim did not actually say the word "dotard," it was translated that way, Mashable reported. The dated word choice might come from how Kim's statement was translated by state news agency KCNA, CNN reported. The actual translated quote: "I will surely and definitely tame the mentally deranged U.S. dotard with fire." In Korean it was written as "늙다리미치광이" ("neulg-dali-michigwang-i"), which literally translates as "old lunatic."

Later in the KCNA translation of Kim's address, the North Korean leader advises Trump to "exercise prudence in selecting words," CNN reported.

President Donald Trump tweeted Friday morning that Kim “was obviously a madman” and “will be tested like never before.”
