True enough, using OC in conversations isn't generally harmful if it's respectful and attached to platform policies. However, some people can misuse OC in terms of spreading misinformation, or just personal data without consent. Users have questions about Oc meaning slang?, If it is your own OC, it's completely safe, but if it can be someone else's, credit should be given. For example, in normal talks, a casual person would use OC slang to simply refer to something new and original, as in, "That's my OC idea for a project." But then again take note of how it's being used, especially online.
