Mathgate 

A scandal that erupted in the United States in 2009 when reports of jobs saved or created by President Barack Obama's stimulus plan came into question.

When the numbers were analyzed, serious errors were uncovered that revealed an overestimation of jobs saved, as well as the creation of jobs in Congressional districts that didn't exist.

As the story unfolded, it became quite apparent that calculating the number of jobs saved or created was an exercise in futility, since it was nearly impossible to determine if the equation used was accurate enough to make such grandiose claims.
Some government worker (GW): "Thank god for the stimulus plan, or I would have been fired."

Some skeptical dude (SD): "How do you know that?"

GW: "Shut the hell up. You hate Obama because he's black, just admit it!"

SD: "Not true. But just like Dick Nixon, Barack is lying to you and Mathgate will be his downfall."

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.
