Urban Dictionary Definition Gestation Period 

The period of time from the point of submission of an Urban Dictionary definition until the point when the submission is either approved for publication or the definition is rejected and not published. The Urban Dictionary Definition Gestation Period can take from minutes to hours or it can take up to several weeks end. There is no explaination for the time variance nor is there a way to determine what the actual definition gestation period will be.

The gestation period for the birth of a human being is far more predictable and accurate than the Urban Dictionary Definition Gestation Period.

"These mass castrations were done just after the battles, in order to sell the new eunuchs to the merchants of slaves that usually followed the armies".

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.

I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
