A typo in a late-night tweet from the President of the United States has become the word on everyone's lips - covfefe.
Donald Trump tweeted shortly after midnight on Wednesday, saying: "Despite the constant negative press covfefe".
Not only did he spark wild speculation over why he did not finish his sentence but he triggered an internet frenzy and coined a new term.
Within hours of Mr Trump's latest attempted, and apparently aborted, attack on the media, #covfefe was trending worldwide and mentioned more than 1.4 million times.
The tweet had more than 120,000 retweets, putting it among his most retweeted, before it was deleted several hours later.
