What does bonce mean?
"Bonce" is an informal British English noun meaning a person's head. It belongs to the same family of affectionate, comic slang terms as "noggin" and "noodle," and it is used almost entirely in light-hearted contexts: someone might scratch their bald bonce, take a knock on the bonce, or be told something daft has gone into their bonce. The word carries no offensive weight; its humour comes from its bluntness rather than any insult, which makes it a staple of friendly banter, sitcom dialogue, and tabloid headlines. The word's origins are obscure — it emerged in nineteenth-century Britain, and etymologists have never settled on a convincing source. Beyond the head sense, older speakers may recall a second meaning from the playground: in marbles and in the game of conkers, a large or unusually hard specimen was also called a bonce. For anyone writing about British colloquial speech, bonce is a small but characterful word that instantly signals an informal, jokey register.
(Informal, chiefly British) A person's head.
"He ruffled the boy's hair over his bonce and sent him off to bed."
Humorous and affectionate in tone; avoid in formal writing.
A large playing marble; in the game of conkers, a hard, prize-winning horse chestnut.
"His prized steelie was the finest bonce on the street."
Now dated; found mainly in reminiscences of mid-twentieth-century childhood games.
Regular plural; used when referring playfully to multiple heads, e.g. of a group of people.
"Three bald bonces nodded in agreement at the back of the pub."
In the schoolyard game of conkers, a particularly hard, winning horse chestnut was itself called a "bonce" — a nod to the word's other life as slang for a stubbornly solid skull.

Etymology of bonce
The origin of "bonce" is genuinely uncertain. The word first appears in written records in mid-nineteenth-century Britain, and lexicographers have proposed several theories without consensus — some linking it to dialect words for stone or marble (which would fit the marble sense), others to unrelated regional vocabulary. What is certain is that the head sense became established by the late nineteenth century and has remained a familiar piece of British informal speech ever since, while the marble sense faded with the decline of traditional playground games.
How bonce is actually used
"Bonce" is distinctly British and colloquial, carrying an affectionate, comic tone rather than any rudeness. It appears almost exclusively in informal speech and writing, often in banter about baldness, knocks to the head, or silly behaviour. American readers may find it unfamiliar; it has no real currency outside Britain and Ireland. The marble sense is dated and largely confined to recollections of childhood games.
