shitmaster 

One who possesses the ability to clog someone's toilet to the point of OVERFLOW (not merely backup or slow flush) causing shitty water to cover the entire tile floor and parts of the adjacent hallway carpeting. This is not intentional, and happens despite multiple courtesy flushes throughout the act leading to the final shitmastering flush.
Dave: (Running out of the bathroom) Where's your mop bro?

Me: What? Why?

Dave: Your toilet's overflowing man. Shit is literally EVERYWHERE!

Me: You're the fucking shitmaster dude... mad props. Now go clean it up.

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.
