The actor said the incident took place after he made a joke "months ago," and recalls how the offensive term for gay people "was commonly used when I was a kid, with a different application.".

Matt Damon has revealed that he stopped using what his daughter calls the “f-slur for a homosexual,” after a recent joke from the actor prompted his daughter to write “a very long, beautiful treatise on how that word is dangerous.”.

In an interview with the U.K.’s Sunday Times published today, Damon recalls how the offensive term for gay people was “commonly used when I was a kid, with a different application.”.

“I made a joke, months ago, and got a treatise from my daughter.

She left the table,” Damon recalls.
