Like Broscience except the subject is wars. OSINT stands for open source intelligence.

Word of mouth knowledge passed off as fact, primarily among call of duty players who are watching the Ukraine war on Twitter with CNN on mute in the backround. Generally spouted by English speakers with no war or analysis experience of any kind. They sperg out on little details on maps that are being passed around social media. The conclusion is, Russia is always losing.
CNN said that the ghost of Kiev shot down 40 Russian planes. The brOSINT on Twitter estimated the number to be 34 planes. (the ghost of Kiev doesn't exist)

Word of the Day on October 4, 2026
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.
