Khârn the Betrayer 

Khârn is a favorite champion of Khorne, the Blood God from the Warhammer 40k Universe. He has an insatiable lust for blood and is known as the betrayer for his habit of messily dismembering allies nearby him when he runs out of enemies. In fact, the name Khârn is actually derived from the Arabic word for "betrayer". Despite all this, he is actually a pretty great guy.
I just watched Khârn the Betrayer dropkick a loyalist marine into that cluster of Thousand Sons; he exploded into confetti and viscera. He then gave me a high-five that shattered every bone in my arm. What a guy!

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.
