The current back-and-forth of insults between U.S. and North Korean heads of state Donald Trump and Kim Jong-un have been public, prominent and colorful. After President Trump referred to Kim as "Rocket Man" during a speech at the United Nations, the North Korean supreme leader issued a statement referring to Trump as a "mentally deranged U.S. dotard." According to reports, North Korea's communications team has been known to use out-of-date English-Korean dictionaries for translation. (So maybe there's something to the 45th American president's claims that he has the best words.)
Whether the nations' leaders plan to follow up their verbal sparring with actual military force, or whether they're just having a little schoolyard fun at the expense of the rest of the world's already-frazzled nerves remains to be seen. But if nothing else comes of this latest incident, at least the word "dotard" is having a moment. Here's what it means, as well as a few more insulting terms that've gone the way of the dodo, but that we're hoping at some point will enjoy their own renaissance.
