Meaning

An agreeing response meaning 'true,' 'that's a good point,' or 'you're right,' used as a standalone acknowledgment.

Young people in particular use it as a quick agreement or validation of someone else's point. It carries a nuance of being genuinely convinced rather than just politely agreeing.
