Call-out culture is when people point out or publicly shame other people for their actions or words, usually on the internet. It often happens when someone says or does something that other people feel is wrong or unfair. For example, if someone says something hurtful or offensive on social media, other people might call them out for it and encourage others to not support that person. People who call out others are usually trying to make the world a better place by making sure that people who do bad things or say bad things get punished.
