Merriam-Webster couldn't resist the urge to spell-check the commander in chief one more time.

In a response to Justice Department special counsel Robert Mueller's ongoing Russia investigation, President Donald Trump quoted a Fox News report on Twitter early Monday, saying: "Democrats can’t find a Smocking Gun tying the Trump campaign to Russia after James Comey’s testimony. No Smocking Gun...No Collusion."

Twice, Trump misspelled "smoking."

And that's when Merriam-Webster jumped in.

"'Smocking' is a type of embroidery made of many small folds sewn into place," the online dictionary tweeted under a cheeky "Today in Spellcheck Can't Save You" advisory.

Social media jesters, including some Hollywood players, joined in and cracked at Trump's latest Twitter gaffe.

“We’ve got a SMOCKING HOT episode of #AndyCohenLive today! MILEY IS HERE!!!” Andy Cohen tweeted, using Trump's latest Twitter gaffe to promote his XM interview with Miley Cyrus.

Minutes later, Mia Farrow tweeted "smocking gun" with a picture of a pistol made of lace.

Actor Zach Braff and former White House intern Monica Lewinsky both added salt to Trump's typo-wound with a "SmockingGun" hashtag and fire emojis, respectively.
