Split the Casper 

The act of penetrating an uncertain hole. An often risky maneuver, "Splitting the Casper" involves taking aim in the general vicinity of two known holes, where the entire area is occluded, or glazed-over, leaving neither hole fully visible. The penetrating object is then thrust at the goopy mess with the hopes of slipping comfortably into either one of two holes. Often this maneuver results in "Hitting the trailer," which is a less that desired result.
Nine guys deep in her gangbang, Michelle's nether region was a sloppy, uncertain mess, but Big Tom didn't care where he ended up so he closed his eyes and "Split the Casper." Unfortunately for Michelle, he was hitting the trailer this time.

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.
