Acronym for “Cordon And Search Operation”, often used by military and law enforcement agencies. The operation typically involves blocking, or “cordoning” off a specific area where a criminal is believed to be, and then thoroughly searching that area. In recent past, the term has been used to describe operations in Kashmir (India/Pakistan) when there is believed to be a terrorist(s) or millitant(s) hiding or trapped in a certain area.
After an attack at the bus station, the terrorists hid in the local neighborhood. Counter-terrorism and police forces launched a CASO for the area within a half mile of the attack.

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.
