Donald Trump has been mercilessly mocked online after he posted a strange tweet, just hours after Press Secretary Sean Spicer fled his first press conference since the president returned to the US amid a reporter revolt.

“Despite the constant negative press covfefe,” President Trump tweeted after midnight on Tuesday.

The tweet was followed by countless trolling tweets with many people facing confusion as to what this strange word meant.

Within two hours, it had been retweeted more than 60,000 times and “liked” more than 74,000 times — making it one of his most popular tweets in months.

Quickly, the “word” covfefe began trending. 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?” inquired another.

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

Merriam-Webster Dictionary’s reaction:

Some tweets employing “convfefe” offer the option to translate it from Norwegian, though that appears to be a glitch of some sort. “Convfefe” does not appear to be a Norwegian word, either.

Desperate for a definition, some Twitter users came up with a few, such as coffee or a synonym to “The Lion King’s” “hakuna matata.” (It means no worries, for the rest of your days. Some would say it’s a problem-free philosophy.)
