One of Matt Damon’s (50) daughters recently taught her father not to use the words ‘fag’ or ‘faggot’, insulting terms for gays. The actor used them as a ‘joke’ but now knows that this is no longer possible in the current era.

“Then I said, ‘I’m quitting'”

“Those terms were used a lot when I was a kid, but mostly with a different meaning,” Damon told The Sunday Times . He says he recently used it again as a joke in front of one of his three daughters, who are between the ages of 10 and 15, and she protested vehemently.

“She left the table. I said, ‘Come on, it’s just a joke! I say it in the movie Stuck On You! ‘” She went to her room and wrote a very long and wonderful speech about why that word is no more can. Then I said, ‘I’ll stop.’ I understood.”

“The fact that Matt Damon’s daughter had to explain to him that saying a slur is wrong is insane,” one user tweeted.
