Earlier this week, the Turkish Deputy Prime Minister Bulent Arinc insisted honest women should not laugh in public because it is disgusting, reported Telegraph online.
Females staged a protest on Twitter, setting up a campaign with the hashtag #DirenKahkaha, which translates to Resist Laugh, and posted pictures of themselves laughing in open spaces.
Watson, an ambassador for United Nations women, joined in and shared a picture of herself having a giggle at an outdoor restaurant.
