noggin

A noggin refers to someone's head or brain.

The word "noggin" is often used informally, and it can mean either your physical head or the idea of thinking. For example, if you hit your noggin on something, you might feel a bit dazed. But when people say "use your noggin," they're asking you to think carefully about a problem. It's like saying "think with your head." If someone says, "I need to get some rest to clear my noggin," they mean they want to calm down and focus their thoughts. The word is used in casual conversations, especially when people are joking around or being playful.
