silent laughter 

When something is so funny, or you are in a state of such slap happiness, that regular laughter transforms into an almost silent and uncontrollable activity. Usually accompanied by tears, silent laughter is most likely the best kind of laughter. You have to make a conscious effort to remember to breathe as your lungs lose air fast in the process of silent laughing. Your ribs start to ache and you begin to wonder if you'll be physically able to take a deep breath before resorting to more silent laughter. Friends and family may laugh at you in this state, or they may be joining in right next to you. Concerned strangers will stare at you and seriously consider finding you help, or they may just hide you from their children.
After I mentioned an inside joke, I looked over to my friend who was doubled over with silent laughter.

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.
