 Do you live in the city that swears the most? Well, if you live here, you probably need to wash your mouth out with soap. According to a new study, Americans cuss 21 times a day, starting at just 11 years old. How would you like to s***? But residents in Columbus, Ohio, they swear up, load, 36 times a day, and mostly at work. So if you're sensitive to colorful words, avoid Columbus and go here instead. Although, studies have shown that swearing could be a sign of intelligence.
