Well, yes, to put a finer point on it. I meant, if it has been spoken [in the context of a conversation and understood by more than a single person in said conversation], it is a word. I don't think it needs to be defined in a dictionary or agreed upon by a committee in order for it to become an official word. Even if you don't agree with it.
A dictionary is a good place for someone to confirm the meaning of a word, and in the context of a professional written piece- it's probably wise to stick to words that can be looked up in this manner. But, on the other hand, YOLO.
