noddle
Slang for head
Noddle is an informal, somewhat old-fashioned word for head—the thinking part especially: Use your noddle.
It appears most often in British English and carries a jocular tone, treating mental effort with gentle mockery.
The word suggests working something out rather than raw intelligence.
