Blockhead, dummy, numbskull. A common, traditional derogatory noun used to describe a stupid, slow-witted, or oblivious person. Historically, the word referred to a wooden block, mold, or cobbler’s last used for shaping hats or wigs. Over time, it shifted metaphorically to describe someone with a head as empty or dense as a block of wood. It is considered a mild to moderate insult — rude and dismissive, but completely clean of any mat or severe vulgarity.
— Вы болван, Николай Иванович, — продолжала Маргарита, — скучный тип. И портфель у вас какой-то истасканный, и вообще вы мне все в такой степени надоели, что видеть вас больше не могу. Улетаю от вас.
You’re an idiot, Nikolay Ivanovich, Margarita continued, a boring guy. And your briefcase is all worn out, and I’m so fed up with you that I can’t stand to see you any more. I’m leaving you
(Михаил Булгаков, Мастер и Маргарита, 1929-1940)
