blackwhite

Newspeak word, and one of the pillars of Ingsoc. Like many Newspeak words, it has two contradictory meanings. In a positive sense, it means someone who is able to believe that black is white, or that two plus two makes five, if the Party wishes it. In the negative sense, it means someone who believes that black is white when it is obviously not (i.e. only if the Party does not wish it to be).
"How many fingers am I holding up, Winston?"
"Four! Four! What else can I say? Four!"

Another way, albeit a lazy one, to spell the glitchfest that was the videogame, BlackSite: Area 51. It can also be abbreviated into BS, which is, ironically, a common way to abbreviate bullshit on the internet.
"Can you guess what videogame I bought today?"

"I hope it wasn't Blacksite. I play videogames to have fun. And that particular videogame was so bad that it gave me testicular cancer."

"Uh... yeah, I mean, no, I got that Madden."

"Thank goodness."

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.
