Bolivian Marching Powder 

"Bolivian Marching Powder" appears in Bright Lights, Big City by Jay McInerney published in 1984. The main character describes the brain and inner soldiers marching around once they've been stimulated with cocaine.
"All might come clear if you could just slip into the bathroom and do a little more Bolivian Marching Powder. Your brain at this moment is composed of brigades of tiny Bolivian soldiers. They are tired and muddy from their long march through the night. There are holes in their boots and they are hungry. They need to be fed. They need the Bolivian Marching Powder." - Bright Lights, Big City, Jay McInerney, 1984

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.
