caboche

Caboche is a French slang noun meaning the head or skull. Used in informal speech, it can refer to the physical head, but more often it is used figuratively to denote intelligence or decision-making, similar to how English speakers might say “use your head.” In everyday conversation, caboche can carry affectionate, playful tones among friends or stand as a mild insult when directed at someone’s intelligence, depending on context and delivery. Because it is informal and somewhat rough, caboche is generally avoided in formal writing or formal settings.

The etymology of caboche is not definitively established. It is part of older French slang with attestations since the 19th century, but precise origins remain unclear. Over time, its usage has continued in popular culture, including conversations, music, and other media, where it helps convey a rough, colloquial voice.

In modern French, caboche exists alongside more formal terms such as tête and crâne and can appear in idiomatic expressions or colloquial phrasing that emphasize a blunt, everyday register. Its acceptability varies by region and social context, and speakers typically adjust tone to avoid unintended offensiveness.
