b) when 3 total strangers, a male and two females, sit in a row at a public place such a park bench or a city bus, the male sitting in between the two women, and the guy randomly decides to hook up with the woman sitting to his left.

RT left hook 

RT left hook is one of the most devastating punches a person can ever receive. Fortunately, only 4 people have experienced such a blow but the impact from these blows has been devastating not only for the recipient but for their family members and doctors who have had to care for them as well. An RT left hook essentially is a left handed punch. What differentiates it from any other left hand punch is that it is immensely more powerful, dangerous and potentially deadly. IF you would really like to scare off a bully or take a more authoritative position amongst your peers, threaten them with an "RT left hook".
-How did you dummy him? "I gave him the RT left hook!"

This is sure to leave victims and observants speechless and most likely, very disturbed.

Leftbook 

Leftbook is a large group of Facebook members that inhabit facebook groups that promote social justice, memes, and leftist thought (proponents of socialism, communism, and marxist-leninism are all represented in these groups.) They often communicate through tagging other Leftbook groups with funny names, like "what if phones, but too much," "sounds like internalized misogyny but ok" and "thank mr banky."

Leftbook 

Leftbook is a group of Facebook groups that are run by very left-wing admins and moderators. They are not united under one group of leaders, but rather under a general very left-wing ideology. They are especially known for advancing modern "social justice" causes and frequently banning users. This tends to create a toxic environment where people are constantly worried about being banned for expressing any view that offends anybody. The groups frequently require users to oppose capitalism, support modern feminism, defer to the opinion of any member of a minority group (even if other members of that group do not always agree), constantly apologize for their own privilege if they are white/male/straight, support Antifa, unquestioningly support the opinions of mods, etc. This basically shuts down any dissent because those people either get banned or are afraid to speak up. In order to avoid being banned, many members dogpile anyone else who comes under criticism as a way to virtue signal and build their own reputation.

These groups have come under fire from other leftists for being hostile, unintentionally being ableist because many autistic people struggle to navigate their byzantine social norms and get banned without being given an explanation for what "mistake" they made, being counter productive by pushing people away from the left, and of course for being authoritarian.
I was a member of a Leftbook group until they banned me for saying that we should not totally disregard the opinions of white men because of privilege.

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.
