Morosaurus

A semi aquatic monster/dinosaur that comes out and beats kids with anything available. If it be a pole or a canoe paddle, no one is safe. A morosaurus is very protective of his turf and will defend it at any cost. If you ever run across a morosaurus, the only way to escape is to yell "You won't" or "Square Up" as loud as you can. He will see it as a very offensive act and will scurry off into the wilderness.

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.
