At 12:06 a.m. Eastern time Wednesday, President Trump tweeted a strange sentence fragment.

“Despite the constant negative press covfefe,” the tweet read. That was it. It ended abruptly, as if someone stopped him, or he stopped himself, or perhaps he never meant to send it.

No, “covfefe” isn’t a typo, at least, not on the part of The Washington Post.

Within six hours, it had been retweeted more than 127,000 times and “liked” more than 162,000 times — making it one of his most popular tweets in months. By then it had become a massive Internet joke.

By 5:48 a.m. EDT, the tweet had been deleted. (The Washington Post saved an image of it earlier in the night.)

Twenty minutes later, a new tweet replaced it:

But by then the “word” covfefe had been trending all night. One company even appeared to have made a shirt with that odd combination of letters written across the front in bold, block letters.

“Don’t talk to me until I’ve had my #covfefe,” wrote one user.

“What’s even the point of CNN if they’re not going commercial-free with #covfefe coverage?” inquiredanother.

“The next time I go to Starbucks I’m gonna order a grande #covfefe,” wrote one thirsty user.
