Profanity is when people use bad words or say things that are meant to be hurtful or disrespectful to others. Just like we use good, polite words to be kind to one another, some people use bad words to be mean. These bad words might be words that your parents or teachers have told you not to say, like "shut up" or "stupid" or even worse words that are used to insult others. It's important to try to be kind to others and not use bad words because they can hurt people's feelings and make them upset. Plus, using profanity can get you in trouble with grown-ups or authorities!
