What does bollock mean?
'Bollock' is a coarse British English term for a testicle, almost always encountered in its plural form, 'bollocks'. Beyond the anatomical sense, the plural carries two well-established figurative meanings in Britain: it can denote utter nonsense or rubbish ('that's a load of bollocks'), or, in the idiom 'the dog's bollocks', it can paradoxically signal excellence — something considered the very best. A related derivative, 'a bollocking', describes a vigorous dressing-down or scolding, typically delivered by a boss, teacher, or parent. The word descends from Old English 'bealluc' and belongs to an old Germanic family of words connected with swelling or roundness, making it a genuine survivor of early English vocabulary rather than a later borrowing. Vulgar in register, it appears freely in informal speech, comedy, and popular journalism but would be out of place in formal writing. Its blend of crudeness, humour, and expressive range has made it one of the most recognisably British swear-adjacent terms.
nounA testicle; chiefly British vulgar slang, used both anatomically and figuratively, often in the plural as 'bollocks' to mean nonsense or rubbish.
- (vulgar slang) a testicle
- (in plural 'bollocks', chiefly British) nonsense, rubbish, or something worthless
- (in 'a bollocking', chiefly British slang) a severe scolding or reprimand
"The doctor's blunt diagnosis left him clutching himself and swearing about his bollocks."
"He doubled over when the cricket ball caught him square in the bollocks."
"The manager gave the whole team a bollocking after that shambolic first half."
Almost always used in the plural; the singular is rare outside medical or deliberately emphatic contexts.
"He was kicked squarely in the bollocks during the scrum."
In Britain, saying something is 'the dog's bollocks' is high praise — the same word that means testicles also tops the scale of approval.

Etymology of bollock
The word derives from Old English 'bealluc', meaning testicle, which traces back through Proto-Germanic '*balluz' to the Indo-European root '*bhel-', meaning 'to swell'. This same ancient root produced a wide family of English words concerned with roundness or swelling, including 'ball', 'belly', 'boulder', and 'bulk'. Germanic cognates appear in related forms across languages such as Old Norse and Middle Dutch. The figurative use of the plural to mean nonsense developed in British slang, while 'a bollocking' emerged as a term for a harsh scolding.
