Prig

Prig is a word that is used to describe someone who thinks they are better than everyone else. It's like the person who always raises their hand in class and acts like they know everything, even if they don't really understand the topic. They might talk down to other people, saying things like "Well, actually..." or "I can't believe you didn't know that."

Basically, being a prig means that you have a big ego and you're not very humble. It's not a nice thing to be called, because it means you're not very kind or friendly to other people. If someone calls you a prig, it's a good sign that you need to work on being more humble and respectful of other people's opinions.
