Normally their profession consists of teaching, preferably Spanish. She is loving, caring, and gullible. When catching her students cheating she feels very accomplished, even though the rest of her class is cheating as well and has been for the whole year. we love hearing about her personal life, especially her cream puff son, and her other son who was raised right. The students writing this are her favorites although she may deny it, to protect her least favorite student's feelings. We love Mrs O, and plan on visiting her every period of every day, unless we are blessed to have her again.
Mrs O didn't see me cheating bro!

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.

Pee Calculus

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.
