Is OC slang harmful for kids to use?

The slang term "OC" is usually harmless for kids to say. OC meaning is  "original character," which is something widely used in creative communities where people design their own fictional characters for stories, comics, or role-play. If a child is interested in OCs, it generally would mean the child enjoys being creative. Parents must keep in mind that OC can have different meanings in texts, and some online sites will permit people to share content that is not appropriate for younger audiences. The best thing to do is for parents to direct kids toward safe platforms where they can create and share OCs in a positive environment.
