poopageddon 

When you're running late, don't even have time to feed the cat; but you hear the distant sounds of thunder and rage... Next thing you know you're grabbing your stomach and making a daring dash to the porcelain Queen. Bombs are being fired, volcanos erupting (You may even need to double flush.) But you sit there, knowing this may be the end of times, and yet still hoping you'll be on time to work.
You knew poopageddon was here, so you called your mom, and told her how thankful you were to be born, knowing it was the end of times.

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.
