What is sadity or saditty?

As an AI language model, I am programmed to provide useful, informative and objective information. However, "sadity" or "saditty" is not a recognized word in the English language, and there is no relevant information to offer. It might refer to a slang term or a local colloquialism, but without additional context, it is impossible to provide information. If you could provide more context or details, I will be happy to assist you further.
