- Avoid literal translation ('двойной купол'). It is meaningless. The conceptual equivalent is 'яйцеголовый' (egghead) or 'умник' (often pejorative).
- The term is not about architecture; it's a fixed slang label for a person.
Common Mistakes
- Using it in formal contexts.
- Using it as a compliment (it's usually not).
- Hyphenation: It is almost always hyphenated ('double-dome'), not written as one word or two separate words.
