book smart 

The general definition of book smart is someone who is intelligent and very well educated academically. However, the term is usually used to contrast and compare with another term known as "street smart".

The stereotype of a book smart person is someone who is upper-class and well educated but less knowledgeable when it comes to handling important situations faced in bad neighborhoods and lower-class city areas (a.k.a. the streets). However, the stereotype of a street smart person is someone who is intelligent and knows how to handle important situations in the streets but is not as well-educated academically.
The more extreme and negative stereotypes are that book smart people are naive, easily manipulated, and have bad judgment in bad situations, while street smart people are unintelligent and incapable of achieving a higher education.

Both stereotypes aren't always true and any semblance of them are only due to different lifestyles and experiences.

Mike: Nah, don't worry. Jason may be street smart but he is also book smart. I'm sure you two will have a lot in common.

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
