Group theory 

Field of abstract algebra dealing with how different symmetries relate to each other (e.g. are they equal? parts of each other? "multiply" to give some other group we want?)
There's a nice VISUAL introduction to group theory which is (imo) watchable at mid-high school levels (15+ yo ish): 3Blue1Brown's video currently titled "Group theory, abstraction, and the 196883-dimensional monster"

Group Chat Theory 

Group Chat Theory is the unofficial theory that all big non-work group chats follow a set structure:

1. A group chat is created that’s just you and your close friends for actual discussion and funny conversations, and all is well and good

2. Your friend eventually insists on adding their friends that you either don’t know or don’t like, but they’re eventually added in, even if you do try to prevent it

3. Those friends either immediately cause chaos, or will just start adding THEIR friends too. Now the group chat is full of randos that are 99% of the time unfunny rude dickheads.

4. Those randos then quickly devolve the chat into the following:

- Bulling someone
- Arguing about beef between each other you either don’t know or don’t care about
- Fill the chat with shitposts instead of actual discussion
- Spam unfunny and illegal shit like gore, porn, drug dealing or more cause they think it’s cool. This then leads to a “Group Chat got leaked…” situation, where the group chat gets leaked to the police or the public, and said unfunny, criminal randos either run away and escape, inevitably to cause another Group Chat Theory in the future, or get caught by authorities and arrested.

5. All of this continues until the group chat meets its metaphorical breaking point, and is either abandoned (otherwise known as a “Dead chat”) or deleted by the owners/taken down by the police.
“Bro that group chat fell off, everybody’s just being a dickhead on there, we should create a new one”

“Yeah bro, that’s literally Group Chat Theory”

“Jesse what the fuck are you talking about.”

Theory of Constructed Groups

Zooming in from communities: the idea that any social group, from a corporate department to a friend circle, is an active construction where roles (leader, clown, skeptic), norms (inside jokes, unspoken rules), and purpose are negotiated and performed. The group doesn't exist before this interaction; it is constituted by it. "Team spirit" isn't a gas that fills the room; it's a practice the team builds through specific actions.
Example: "The project 'team' was a disaster until we unconsciously used the Theory of Constructed Groups. We instituted a stupid Monday meme ritual (building a norm), assigned Nick to be the official progress nag (constructing a role), and started calling ourselves 'The Bug Slayers' (narrating an identity). The same people became a functional group through these tiny acts of construction. The group wasn't the people; it was the pattern we built between them."

Theory of Secret Power Groups

A more pluralistic and less monolithic version of the "Global Elites" theory. It suggests the world is shaped by the covert competition and occasional collaboration of multiple hidden power groups: international finance networks, old aristocratic bloodlines, secret societies (like Skull and Bones), organized crime syndicates, and ideological cults. The world stage is their chessboard, and nations are their pieces.
Theory of Secret Power Groups Example: In this Theory, the rise of a tech mogul might be attributed not to genius, but to backing from a Secret Power Group of Silicon Valley venture capitalists with ties to intelligence agencies, using him as a proxy to control data and social networks, while a rival group of old-money industrialists tries to sabotage him.

Theory of Power Groups

A mainstream sociological concept stating that in any complex society, power is not held by a single entity (the state) or the masses, but is contested and exercised by a plurality of competing groups: corporations, unions, professional associations, NGOs, media conglomerates, and religious institutions. Politics is the process of temporary alliances and conflicts between these groups. It’s pluralism, but where the playing field is not level and some groups have vastly more resources.
Example: Environmental policy in a country is not set just by the government. According to the Theory of Power Groups, it's the outcome of a brutal lobbying war between the fossil fuel industry group, the renewable energy trade association, environmental NGOs, and utility unions, each pulling on different levers of power within the legislature, courts, and media.

doorwall 

A door wall is a sliding-glass door or patio door. The term is yet another example of banal Michigan vernacular, where in the residents latch on to company names, trademark names, marketing terms and product names from local companies. The terms become embedded in the local vocabulary and eventually become accepted as actual valid words and phrases. In this case the term comes from Wallside Windows in Taylor, MI (a large window manufacturer), where 'door wall' is their created word for sliding-glass door.

Frothability 

The measure of an emotional and over zealous consumer in an upwardly charging market, also known as a bull market. It's characterized by rising asset prices, increased investor confidence, and favorable growth in the markets, bro.
The frothability was evident as over-zealous consumers eagerly engaged in bidding wars, driving property prices to unsustainable levels reminiscent of previous speculative bubbles.
