alter–egoism 

expanded egoism that is focused on alter ego, a significant other for whom you care as much or even more than for yourself.
Chekhov's Darling is a perfect example of alter–egoism: she gives herself up to her loved ones and lives solely by their interests and feelings. This is her way to cherish her own ego.

Alter–egoism is different from altruism. Altruism is indiscriminate selfless concern for the well-being of others, whereas alter–egoism is very selective: it is directed on alter–egos, i.e. the chosen ones, and thus retains certain qualities of egoism.

A political ideology that states that the only important thing should be yourself, and all actions should be done out of self-interest and selfishness. For dickheads who don't even wanna conform in an anarchist society. One of the main beliefs of egoism is the concept of 'ghosts in the mind', more commonly called 'spooks'. These refer to societal constructs that influence how somebody should *really* be acting. Don't bother calling out their ego, they take it as a good thing.

Egoism by The Pasta Man October 1, 2020
an anarchist school of thought often called "Anarcho Individualism", "Anarcho Egoism" but usually just shortened to "Egoism"
The idea was originally proposed by the German philosopher Max Stirner in his book "The Ego and Its own" or also known as "The Unique and its Property"

it says ideas like The State, Religion, God(s), Laws, Capitalism, Morality, The Market and Societal Obligation are "spooks" or ideas that suppress the individual sense of self (aka the "ego") while not actually being real just illusions created by our masters to suppress us (aka "ghost of the mind" as Stirner would put it)
One of its main idea is that the ego (your sense of self) should strive to do things that make you happy and give you fulfillment rather than being restricted by society

It is just "Do whatever you want I don't care"
Person 1: I believe in Egoism, I should be able to do what I find personally fulfilling rather than be ordered around by spooks like The State or society

Person 2: Sir this is a Wendy's

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.
