Thunderdump 

A violent bowel movement, usually loose, which the person may have been storing for some time due to lack of access to ammenities. Propelled by a buildup of gas caused by the fact that a fart during this time would have resulted in a follow through.

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.
