The word "discourteous" means showing rude or disrespectful behavior towards others. It is important to use this word in situations where someone is being impolite or not treating others with kindness. For example, if someone doesn't say "thank you" when someone helps them, you can say that person is being discourteous. It is a formal word, so it may be more appropriate to use in serious situations, such as in the workplace or with people you don't know well.
