Headache is a common medical condition that is characterized by a throbbing or pulsing pain in the head. It can be caused by a variety of factors, including stress, dehydration, and certain medications. The term 'noogie' is slang for a playful punch or pinch to the head or neck area. This term is often used to describe the sensation of a headache, as it can feel like someone is giving you a noogie.
