The term STOP O.K.'ING can be summarized as a BAN on approval or authorization. This means that any action or decision that requires approval or authorization will no longer be allowed. This could be used in a variety of contexts, such as a business setting where certain decisions need to be approved by a manager before they can be implemented. It could also be used in a school setting, where a teacher may need to approve a student's request before it can be granted. In any case, the term STOP O.K.'ING implies that no further approval or authorization will be given.
