A long, friendly conversation or chat; informal gossip or friendly talk.
British slang from the 1890s, combining 'chin' (jaw) and 'wag' (to move back and forth). The image is of jaws moving continuously during talking, humorously suggesting endless chatter.
Chinwag perfectly captures how slang uses physical metaphors—your chin literally wags when you talk a lot, so British speakers created this playful term that's both descriptive and affectionate about people who love conversation.
