Chicago Girl 

A woman exhibiting above-average attractiveness from the neck up, but who is unacceptably - and often surprisingly/disappointingly - overweight in the body. The term stems from Tucker Max's contention that Chicago's extremely short swimsuit season gives the otherwise attractive women there little incentive to exercise.
I met this chick online and saw her headshot and she was fine as hell. But when I finally saw a full-body shot she turned out to be a total Chicago Girl.

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.
