While on the presidential campaign trail late in 2015, Donald Trump boasted that he had “the best words.” In a tweet fired off early Wednesday morning, he may have revealed one of them to the world: Covfefe.

While “covfefe” was likely a typo, the post remained online for at least an hour with no followup or correction, gathering more than 100,000 likes, replies and retweets combined. That caused this new entry into the lexicon to instantly trend:

UPDATE: Trump deleted his original tweet shortly after 6 a.m. on Wednesday, and replaced it with this one:

Who can figure out the true meaning of "covfefe" ??? Enjoy! — Donald J. Trump (@realDonaldTrump) May 31, 2017

He did not explain what happened with the original message or why it wasn’t changed for more than six hours.
