Socially Concerned 

Ostensibly it means caring about society. Being concerned about the things that are wrong with society such as increasing violent crime, an increasingly stressed health service, the marginalisation of the disadvantaged members of society, the list is pretty much endless; those who are truly socially concerned then try to do something about it. Unfortunately as in the case of the chattering classes the socially concerned individuals only pay lip-service to whatever cause is fashionable and they do sfa.
Most so-called socially concerned just talk about the latest fashionable cause, they don’t actually do anything to help.

Post Concert Depression 

Also known as PCD, it is the depression after your favorite band or singer's concert. You feel like you miss them a lot even though they don't know you, and you don't know what to do with your life because your life is so boring out side of a concert. Sometimes, symptoms are so bad that you cry a lot, can't eat anything, and don't talk to anyone. A lot of the time you'll be looking at the pictures or videos you took at the concert or watch other people's recordings on YouTube.
Hey, Susie, you look really sad. Didn't you have a good time at the concert you went to last night?

Nah, man, leave her alone. She must be suffering with post concert depression.

Post concert depression 

After seeing your favourite singer(s) play live, you might get PCD, post concert depression. Not cause they weren’t what you were expecting, but cause you saw your idol just a few feet in front of you, and you realise you might never see them again. (Lazy description of it)
Person A: what’s up with B?
Person C: they saw Twenty one pilots yesterday.
Person A: why are they still crying?
Person C: PCD
Person A: what’s that?
Person C: post concert depression.

Concerned Adult Brigade 

Often called "CAB" for short, the concerned adult brigade is any group of equally disgruntled people (usually 35 or older) united together for an absurd and often unnecessary cause. These are the people who run neighborhood watches, regularly attend PTA meetings, deem things "inappropriate", complain to authority figures, overreact on issues, chaperone parties, file noise complaints, call parents, actually check movie and game ratings, work at the FCC, and generally meddle in the affairs of the youth.

Members of the concerned adult brigade come in many forms though are recognizable by their running-for-senator hairstyles and "sensible" shoes. Almost always women.
Girl #1: "So I watched sesame street yesterday for no reason. I thought you said Katy Perry was gonna be on it!?"

Girl #2: "Ugh, she was! But the Concerned Adult Brigade saw her outfit and started bitching. So they pulled the episode off the air."

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.
