In a poll of more than 1,000 American adults, 74% said they’re frequently or occasionally subjected to profanity outside the home. And 67% said cursing has increased during the past 20 years.

But there’s good news, too. Last year, 14-year-old McKay Hatch started a “No Cussing” club at his school. Before long, the club had more than 20,000 members, who take the following pledge: “I won’t cuss, swear, use bad language, or tell dirty jokes. Clean language is the sign of intelligence and always demands respect. I will use my language to uplift, encourage, and motivate. I will leave people better than I found them!”
