Okay kiddo, let's talk about Cantonese profanity. You know how sometimes people use bad words when they are angry or upset? Cantonese is a language spoken in China and there are some words in Cantonese that are considered very bad and rude to use.
Some of these bad words refer to body parts, like the ones used to go to the bathroom. Other bad words insult people and call them names. These words can hurt people's feelings and it's not nice to use them.
It's important to remember that even though some people might use these bad words, it's not okay to say them. It's better to use kind words that don't hurt anyone's feelings. And remember, just because some words are considered "bad" or "profane" in one language or culture, that doesn't mean it's the same in another language or culture.
