butterfasting 

Butterfasting is the best way for teenagers who troll pro ana boards to lose weight.

The butterfast is amazingly simple. All you do is eat a stick of butter in the morning (can be melted or nonmelted). For the rest of the day, you can basically eat whatever you want until the butter passes through. It seems completely illogical, but the butter doesnt lie.

I think it coats your stomach or intestines (you know, the part that absorbs the calories?). And the food just passes right on by.

Warning, the butterfast does have a slight laxative effect, but butterfasting is much gentler than laxing.
OMG Anne!! I have prom coming up in a week? I need to lose weight really quick!! Im butterfasting until I drop ten pounds. You in?

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.
According to the boffins downstairs, the murderer used a serrated blade.
