This afternoon US President Donald Trump tweeted, "Despite the constant negative press covfefe."
Within 20 minutes, it had been retweeted 13,000 times, liked 16,000 times, and "covfefe" was trending worldwide.
So what is covfefe? A typo of coverage? The tweet was sent about midnight in Washington, so maybe a plea for coffee? His password?
It seemed even the POTUS did not know, tweeting just after 6am DC time, "Who can figure out the true meaning of 'covfefe'???"
Twitter, as it often does, was full of jokes within minutes of the initial tweet.
And if you're confused how to pronounce "covfefe", read this whole thread.
