"Septum Theory" Theory

A dismissive phrase invented as a lazy insult toward women with septum rings. It’s most often used when the person insulting can’t actually respond to what a woman with a septum piercing is saying — so instead of addressing her point, they reduce her to her jewelry.

It’s not really a “theory” at all — it’s a cop-out comeback.

People lean on “Septum Theory” when they’re out of arguments, turning someone’s appearance into the debate itself.
Her: “That’s actually factually incorrect, here’s the source.”

Him: “Uhh… Septum Theory.”

Translation: “I don’t have a real argument, so I’ll just insult your piercing.”

Her: Says anything that goes against men in general

Him: Septum theory strikes again.

Translation: I have no argument.

Aka "Septum Theory" Theory. The theory that men will find anything they can to try an degrade a woman, logical or not.

Cosette Theory

Cosette Theory is the scholarly examination of Cosette’s linguistic idiosyncrasies, particularly focusing on recurring typographical errors and the identification of consistent patterns in her lexical mistakes. It extends further into the analysis of habitual behaviors and the prediction of her actions based on linguistic and behavioral trends. In essence, Cosette Theory serves as an overarching framework for understanding Cosette’s unique communicative and behavioral patterns.
Gerbert: "Yo, Cosette has dropped the word 'ducking' like 6 or 7 times in the last hour. What’s the deal with that?"
Zoidberg: "Have you even read up on Cosette Theory??"
Gerbert: "Is that a dropper reference or something. This is the 2112th time you've mentioned that"
Zoidberg: "Gerbert you have mental covid"
Horse: "Who doesn't?"
WhoDoesnt: "Fuck my chungus life"

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"
