Matt Damon has vowed to never use the "F-slur" again after one of his daughters called him out for the same.

The Oscar-winning actor recently opened up about using a derogatory term known as a slur against members of the LGBTQ+ community. However, he decided to erase the word from his vocabulary after one of his four daughters expressed dismay over it, E! News reported, citing U.K.'s "The Sunday Times."

Damon said his child, whom he did not specifically name, wrote a long explanation why he should never use the "F-slur" again.

"The word that my daughter calls the 'f-slur for a homosexual' was commonly used when I was a kid, with a different application," the "Stillwater" actor explained as per E! News. "I made a joke, months ago, and got a treatise from my daughter. She left the table."

The "Jason Bourne" star said he tried defending himself from his child. "I said, 'Come on, that's a joke! I say it in the movie Stuck on You!'" Damon recalled.

"She went to her room and wrote a very long, beautiful treatise on how that word is dangerous. I said, 'I retire the f-slur!' I understood," he continued.

Further, the "Good Will Hunting" actor acknowledged his daughter's point as he read her essay. "It's a fair point. Anybody should be offended by that behavior."

Despite Damon's promise to stop using the word, many still expressed their thoughts about the actor's confession. One of them was "Billy on the Street" creator Billy Eichner.

"I want to know what word Matt Damon has replaced f****t with," Eichner said in a tweet.

Producer Jacklyn Moore also reacted to Damon's remarks. "Remember when the joke was that Ben Affleck was the dumb one and Matt Damon was the smart one?" Because one is dating J-Lo and the other is spending the year of our lord Dolly Parton 2021 bragging about how he just stopped saying 'f-g," she said.

Author Mark Harris also cautioned others against using the slur.

"When I meet a straight man, that split-second assessment--would they say that word to you, would they say it about you, what if they thought you'd never hear it--is still something I'm hardwired to do. An extra safety-check for many of us. For decades," he wrote.
