Definition: Puk is a Hebrew term meaning "to vomit." It originates from the verb "puh" which means to throw food, usually food in one's mouth. This term was commonly used by early Christians for describing human bodily functions such as vomiting. The precise definition varies across different sources, but often includes vomiting due to an illness or injury, and can also be a symptom of something more serious like nausea or diarrhea. Puking is generally considered a normal bodily response in humans. In the context of Jewish teachings and practices, it is considered a sign of spiritual transformation and purification.
