"TOUGH GUYS FOR TRUMP", the president wrote along with the clip.
"I ought to rip you out of your f-ing vehicle!" the biker says to David in the clip.
"I'm sorry I didn't see ya", David says, rolling down his vehicle window while wearing the bright red hat. "Larry David was making fun of you", another wrote. It reveals Larry David defusing a road-rage conflict with an offended biker by donning a purple "Make America Nice Once more" cap.
The MAGA moment is part of the episode's running storyline of Larry wearing the hat as a cynical ploy to avoid people he doesn't want to see.
In "Happy New Year", which first aired January 19, the subject of MAGA hats is brought up during a conversation between David, who plays a fictionalized version of himself, and his best friend, Jeff Greene (portrayed by Jeff Garlin).
"TOUGH GUYS FOR TRUMP!" the president tweeted, along with a bootleg clip from the season 10 premiere, "Happy New Year", in which Larry cuts a guy driving a motorcycle off. "He makes me want to not be anywhere near him", Greene says.
"This is worse than the Thanos tweet", a Twitter user opined. He uses the hat to avoid lunch with a guy and to make sure no one sits beside him at a sushi bar. The acquaintance sees the hat, sees other people scowling in the restaurant and immediately makes an excuse to leave. "It was to say they are obnoxious bullies like Orange Man". People on the left see this clip the way it was intended: a satire of the assholes who support Trump.
It's not the first time Trump has shared a pop-culture joke that reflects poorly on him in its proper context.
As Trump's supporters praised his "grand sense of humor", critics didn't hesitate to call out the president for having "zero self awareness" and "cluelessly tweeting".
"Triggered", a pro-Trump account tweeted in response to the video.
David, who also co-created Seinfeld, has shown no remorse for mocking Trump supporters in his latest season of Curb.
As for David, 72, he was recently asked by radio host Michael Kay if he was anxious the "MAGA" hat joke in Curb Your Enthusiasm's premiere would alienate viewers who supported the president. "Alienate yourselves, go, go an alienate, you have my blessing", Larry said. David replied. He made sure to hammer home his point that he doesn't care about MAGA lover's feelings stating, "No, I could give a fuck!".
