Out Of Character
Out Of Character (abbreviated "OOC") is a phrase used to denote any actions or words which are performed by a writer, and not his or her representative character.
So, for example, if someone were to say that they are "34 years old, OOC," it means that the writer is actually 34 years old, as opposed to their character, who may be an entirely different age.
OOC or "DOOC" (Direct Out Of Character) may be used to within a sim or the subject line of an email to indicate contents that are meant to be taken as Out Of Character communication.
