ratjacket 

Ratjacket is a reputation or 'jacket' for snitching. Once acquired, a ratjacket is typically permanent. In the office and other environments where people become well-known to each other, the ratjacket is a form of social leprosy and can lead to ostracization and worse.
Emma noticed a chilly social thermostat at the office. To her horror, Emma realized she had a ratjacket after singing to management about Jenny and Heather's time-card collusion.

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.

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
