A Doomba is an amalgamation of the Roomba; a series of autonomous cleaning devices made by the company iRobot and various weapons such as knives, chainsaws and fireams which are strapped or somehow attached to the machine. The word "Doomba" comes from the merging of the words "Doom" and the previously mentioned "Roomba". This has recently become popular on various Internet sharing sites.
"Hey Johnny, I strapped some knives to your mom's Roomba, let's watch it go around the room."
"Yeah, now it's a DOOMBA"

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.
