mouse cheese 

Contrary to popular belief, mice really aren't all that crazy about cheese. Sure, they might eat it if there's nothing else around -- a hungry mouse can't be too picky -- but it's far from his favorite food.

If you happen to have a pet mouse, keep in mind that feeding him cheese could even be harmful as cheese is not a natural part of the mouse diet. Stick to fresh fruits and veggies along with high quality mouse pellets to maximize nutrition, with a few sweets and grains thrown in as an occasional treat.

mouse cheese 

Mouse cheese is similar to dick cheese, except from a vagina, generally caused by a yeast infection. Alternately, it is another term for mousetrap cheese or tasteless cheese of questionable quality (although mice don't even really like cheese that much).

Both of these cheeses are decidedly NOT good eats, so don't ya put it in your mouth.

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.
