An unlikely word is trending on Twitter this morning -- dotard.
The insult was a riposte from Kim Jong Un after US President Donald Trump nicknamed the North Korean leader "Rocket Man" at the UN General Assembly.
The unusual word left many people scratching their heads and Google searches for dotard went through the roof.
So, what does it actually mean? Twitter-savvy dictionary Merriam-Webster was quick to come to peoples' aid.
Merriam-Webster defines dotard as "a person in his or her dotage" -- dotage meaning, "a state or period of senile decay marked by decline of mental poise and alertness."
It stems from the Middle English word doten, which was used to describe an imbecile at the time of its introduction in the 14th century.
The Washington Post's Tokyo bureau chief Anna Fifield, though, was quick to point out that the Korean definition of Kim Jong Un's barb was "lunatic old man."
According to Google's Ngram Viewer, which allows users to track the popularity of words through time, use of the word 'dotard' peaked in English corpus in the early eighteenth century.
Obviously, this word is slightly dated -- and some people were left perplexed:
Some people thought Kim Jong Un came out on top of the exchange:
Others just straight up agreed with the North Korean leader:

Mentally deranged US dotard? That's pretty good actually. I'd definitely rather be referred to as Rocket Man. This round to Kim Jong-un. https://t.co/vgZcmcGDKJ
