The expression "cheer up" is used when someone is feeling sad or down, and you want them to feel better. You can say it to a friend, family member, or even a stranger. For example, if your friend is feeling sad because they didn't get the job they wanted, you can say "cheer up, there are other opportunities out there" to encourage them. It's a way of showing that you care and want to help them feel happier.
