North Korean leader Kim Jong Un attacked Trump on Thursday, calling the president a "dotard."
"I will surely and definitely tame the deranged U.S. dotard with fire," Kim said in a statement published by Korean Central News Agency, Korea's official news publication. If you were born in the last 100 hundreds years, you're probably wondering what a "dotard" even is.
A quick Google search reveals that a dotard is "an old person, especially one who has become weak or senile." The Merriam-Webster dictionary revealed much of the world was curious as to what the archaic word meant, noting on twitter that searches for the word were "high as a kite."
The dictionary of record noted the word was the equivalent of "imbecile" and was first used around the 14th century. It is derived from the Middle English word "doten," which means "to dote." The word was used by famous English writer Geoffrey Chaucer in "The Canterbury Tales," and appears in William Shakespeare's work as well, according to the Washington Post.
South Korean freelance journalist Jihye Lee noted Kim's statement literally translates to "old beast lunatic," which was later translated to dotard.
It's not the first time the word has been used as an insult by politicians. The Post noted former President Martin Van Buren was called a dotard around 175 years ago.
Kim's statement comes after Trump threatened to destroy North Korea while speaking at the U.N. on Tuesday. The president followed up his comments with new financial sanctions on the hermit country on Thursday.
Trump and Kim have exchanged insults and fiery rhetoric since the former entered office. Trump's latest jab refers to Kim as a "madman who doesn't mind starving or killing his people." He added that he "will be tested like never before!"
