I don't think you knew you were doing it

So you took that as an accusation of wrongdoing but YOU WEREN'T ALONE in doing it and now you are trying to make it a thing like this was because I "accused you falsely of doing something"

Hym "I don't think you knew you were doing it but SOME OF THE PEOPLE WHO WERE ALSO DOING IT... KNEW they were doing it. And it WAS A THING THAT WAS HAPPENING and IS. And is a problem. For you to assert that we have to care about saying nigger and faggot more than this. No. You didn't know it was a thing. I discovered that it was a thing. You felt attacked because you though I was accusing you but you didn't know anything at the time but by the time you found out about it. You just didn't get it. At any point. You didn't understand what was happening. You didn't want to play ball because I was being offensive and derogatory. And the people I said would suffer (through no fault of my own) for it did in fact have to do so. Even though THEY HAD NOT HAD TO DO THAT INITIALLY. You thought it was something it wasn't. I was flippant about what it was but at a certain point you had to have picked up on some general themes that emerged and you had to have known you didn't know what was going on and at some point you'd have to talk to the actual guy
But you didn't want to do that because you thought I was playing a game or something because I use a 50's announcer rhetorical flourish. 'Don't give him the attention that he wants. Oh! Shit! The kids!' And it wasn't even a set up! IT WASN'T EVEN A SET UP AND YOU THOUGHT IT WAS A SET UP! To TELL THEM THAT... 'don't give hym the attention that he wants. Oh no! Muh kids 😾 now I guess I'll do 'the opposite! Cus he said that one time.' Because you though it was a set up... And then for it to go disastrously wrong and then for you to BLAME ME FOR THAT... And make my life hell as a result of it. I don't think you knew you were doing it. I think you didn't believe me. And were dismissive about it and I was right and it does matter that I was right."

.....Ready now, my baby coming through we getting faded oh i thought you knew Steady now, don't you fall of the edge Everybody lit the party will never end.....

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.
