Inspiration: A meat cutting industry was packaging ground beef when a customer had called asking the price of Cod Fish. After looking up the price of the Cod Fish, the wrapper had continued to package the ground beef without changing the name of the price tags. Thus labelling all ground beef as "Cod Filets"; which sparked the term "Codburger".

Definition: Untrimmed and unwashed vagina -- used so much to a point where nobody would wish to touch it.
She seemed to be a MILF until I saw her Codburger.

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.
