Oc meaning in text?, OC, or Original Content, in a piece of text, might look something like this:
"Hey, check out my new drawing! It's my OC character, and I gave them fire powers!"

Or perhaps in a casual chat:
"Just developed a new awesome game idea—totally my OC!"

So what's interesting here is that usually, people use OC when they are talking about an idea that is only theirs, their character, or their creation. You can find this in many creative communities where users showcase their original work.
