Mangani is the name of a fictional species of great apes in the Tarzan novels of Edgar Rice Burroughs, and of the invented language used by these apes.
In the invented language, Mangani (meaning "great-ape") is the apes' word for their own kind, although the term is also applied (with modifications) to humans. The Mangani are represented as the apes who foster and raise Tarzan.

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.
