How it's used
People almost exclusively use the term 腦囟 in daily life rather than the more clinical 囟門. It is culturally significant because of the common idiom 腦囟未生埋, which is used to describe someone who is naive, immature, or lacks life experience. You will hear this phrase used jokingly or critically when someone acts in a childish or foolish way.

Common mistake
Do not confuse the literal anatomical term with the metaphorical usage. If you tell someone their 腦囟未生埋, you are insulting their maturity, not commenting on their physical health.
