The Merriam-Webster dictionary took to Twitter Saturday to mock President-elect Donald Trump after he misspelled the word "unprecedented" in a tweet early Saturday.

Responding to news that China had taken a U.S. Navy underwater drone out of the South China Sea, Trump initially tweeted, "China steals United States Navy research drone in international waters – rips it out of water and takes it to China in unpresidented act."

He later deleted the tweet and retweeted it with the correct spelling of the word "unprecedented." However, that didn't stop the online dictionary from taking a swipe at the president-elect.

"Good morning! The #WordOfTheDay is...not 'unpresidented'. We don't enter that word. That's a new one," the dictionary tweeted, linking to its definition of the word "huh."

The tweet was extremely popular — likely for its mocking of Trump — and received nearly 25,000 retweets and more than 36,000 "likes" as of Sunday morning.

Merriam-Webster wasn't the only Twitter user to seize the moment to mock Trump. Many Twitter users, mostly Democrats upset that Trump will be president, used Trump's misspelling to say that America should "un president" Trump before his inauguration next month.
