sphincter grease 

sphincter grease /ˈsfɪŋktər - grees (n.):

1. The resulting oily residue as having been rendered from an abnormally abundant and unkempt conglomeration of "swass" (aka. ass sweat).

-This advanced state of natural anal lubricant can typically be found on most hippies, destination vacation attendees, and hobos, and is commonly noted as the 2nd natural state of anal condensation, the first being "swass" and the 3rd being "ass butter." Sublimation is possible in extreme cases, however highly unlikely as sphincter grease plays an integral role in springboarding swass into a semi petrolic, pre-gelatinous state necessary for the achievement of ass butter.

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.
