Donald Trump has teased that his confusing 'Covfefe' social media post from two-and-a-half years ago might not have been and a mistake and could have 'deep meaning'.

Trump re-sparked chatter on the topic after PricewaterhouseCoopers partner Mitch Roschelle shared a tweet that announced a horse named Covfefe won a Breeders' Cup event at Santa Anita, California on Saturday and said it was was 'named after President Trump's famous mistweet'.

It prompted the president to celebrate the triumph of the horse who has now won six of her first eight races, but defend his old Twitter post on Monday: 'Great! But how do you know it was a "mistweet?" May be something with deep meaning!'

Just after midnight on May 21, 2017, he tweeted: 'Despite the negative press covfefe'.

Donald Trump teased Monday that his confusing social media post from two-and-a-half years ago might not have been and a mistake and could have 'deep meaning'.

The thoroughbred (pictured) is named after the same unexplained word 'covfefe' found its way in a late-night tweet made by President Donald Trump two years ago

It's believed the infamous utterance was a mistake because and he meant to type 'coverage' because he then deleted the tweet.

Instead of pretending the tweet never happened, six hours later Trump invited the world in another post to figure out the 'true meaning of 'covfefe' and it went viral.

A year after the bizarre tweet, social media users waxed nostalgic about the typo and even referred to the anniversary as Covfefe Day.

Even Urban Dictionary couldn't come up with a meaning for covfefe. The word's first definition on the site reads: 'It literally means covfefe.'

Another suggests it's 'When you make a mistake, but play it off like you knew what you were doing.' The example included with that definition reads: 'Trump's entire presidency was a real covfefe.'

Since then some people have claimed it's an antediluvian reference that means 'in the end we win'.

Covfefe, the horse, was named by its co-owner Jamie Roth, because she thought the animal was 'special' and the 'name was kind of funny' and it may have proved a good omen on Saturday.

President Donald Trump's original tweet expressing frustration with the media came just after midnight on May 21, 2017, when he wrote 'Despite the negative press covfefe'

Trump never completed the thought or explained the typo, instead leaving social media users to fill in the blanks

The three-year-old filly, won the $1million Filly & Mare Sprint by three-quarters of a length under jockey Joel Rosario. The thoroughbred, a 3-2 favorite with a late surge of money by bettors, paid $5 to win.

Covfefe ran seven furlongs in 1:22.40. Bellafina was second and Dawn the Destroyer took third.

The filly even has its own Twitter account named 'RealCovfefeRacehorse,' and uses the handle @CovfefeHorse, which pokes fun at the president.

On Thursday, the horse's account tweeted 'The Greatest #CovfefeHunt In American History!' in a play off the president's use of 'witch hunt' to describe the current impeachment inquiry against him.

Roth told USA Today she hasn't heard from the White House. 'He's not for me, but obviously he is for some other people,' she said of Trump. 'He just doesn't stand for the things that I believe it. But I believe in Covfefe.'

The stable owner, who acknowledged she didn't vote for Trump, said she was considering naming another horse 'Trump Tweets,' and had reserved the moniker with a breed registry for thoroughbreds.
