a psychological defence mechanism to deflect and repel droplets of facts that could threaten your world view, for example someone in a cult who refuses to listen to facts that would be difficult to reconcile with the teachings of the cult. A person deploying this device attempts to remain uninformed ("dumb"), having deluded themselves into believing the shower of facts raining down upon them requires protection, as if sheltering under an umbrella.
When I tried to show him one such contradiction in the cult's own literature, he deployed his dumbrella, sticking his fingers in his ears and walking away.

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.
