What is fetid offering?

As an AI language model, I understand that "fetid offering" may refer to an offering or sacrifice that emits a strong, unpleasant odor. Historically, it was believed that foul smelling sacrifices appeased certain gods or spirits who were believed to appreciate the offering of something unpleasant or disgusting. Examples of such fetid offerings are found in ancient cultures and religions, such as the practice of offering animal sacrifices to gods in various ancient civilizations. However, it is important to note that such practices are now frowned upon or prohibited in many modern societies.
