What does berk mean?
"Berk" is a piece of British slang meaning a foolish, stupid, or irritating person. It functions as a mild insult, the kind exchanged between friends or muttered in exasperation at someone's incompetence, as in "Don't be such a berk." The word is most interesting for its origin: it is Cockney rhyming slang, a shortened form of "Berkshire Hunt," which rhymes with an extremely coarse word for a woman's genitals that polite society avoids. Because the vulgar original has been almost entirely forgotten by everyday speakers, "berk" now reads as harmless — tame enough for family television and children's comedy — while still carrying a faintly cheeky undertone for those who know the secret. It remains firmly a Britishism, rarely heard in American English.

"Berk" looks utterly innocent, but it's actually Cockney rhyming slang hiding one of English's rudest words in plain sight.

Etymology of berk
"Berk" originated in London as Cockney rhyming slang, an early-20th-century wordplay tradition in which a phrase rhyming with the intended word stands in for it. Here the source phrase was "Berkeley Hunt" or "Berkshire Hunt", which rhymes with a strongly taboo word for female genitalia; speakers then dropped the rhyming noun, leaving "Berk(shire)", abbreviated to "berk". Like other rhyming-slang creations (for example "butcher's hook" for "look"), it allowed speakers to swear covertly. Over time the connection faded and the word softened into general mild British slang for a fool.
How berk is actually used
"Berk" is informal and chiefly British. Though its hidden origin is highly vulgar, the word itself is now considered mild — suitable even on television — and often carries affectionate or jocular overtones rather than genuine hostility.
