Just after midnight, Washington time, on the morning of Wednesday May 31, Donald Trump composed a short tweet. It simply read: “Despite the constant negative press covfefe.”

His words, if indeed that last one is a word (it isn’t), set the twittersphere on fire. Pundits, observers, politicians, comedians and Trump detractors and supporters immediately took to Twitter to offer their assistance in explaining #covfefe in light of the fact that even the Merriam-Webster dictionary had nothing to offer.
