The Evil One 

The quiet new girl who seems sweet until you get to know her. By then it's too late. She follows you everywhere by clinging onto your sleeve wordlessly. She doesn't say much but when she does it's completely unrelated to the conversation or if it's a story, it goes absolutely nowhere. Despite this, she is a beautiful person, even if she does occasionally attempt to possess you.
'Did you see the new girl? She's so hot!'
'I wouldn't. A friend from her old school said she's The Evil One. She left because she caused someone to jump off a cliff'
'Woahhh'

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.
