Meaning "Own Character" an OC is a character made up by a person, to be used literally as thier "own character" for fanfictions,(with or without a character from an anime series) picture ideas, ect. An OC is often a non-human, (i.e. Vampire, Werewolf, ect.) or sometimes an anthro character. It is also often for OC to be in anime-style when drawn.

On occasion, groups of friends will act and speak like thier OCs would, for fun. They often "switch" between each OC and thier own personalites.
Amy: Omg i just wrote a really random fanfic about my OC, Kitty and Nicole's OC, Ben.
Jane: Haha, cool. I just finished Drawing a pic of my OC, Danny!

Jane: (also as OC) Ha, well Jane-chan drew an AWESOME picture of me!
