A: Depends on what you're talking about. It can stand for Orange County (place in California), original character, original content, offensive coordinator (position in american football), of course (though ofc is more common), or something else that i can't think of.

Q: I'm Watching The OC now and surprised by how easily they kiss.
Is this real?

Now I have a question for you.
How many people had you kissed when you were a college student?
