I read both books too and when I saw the title they're what it reminded me of and then it was confirmed when I clicked the link, so it's nice to predict something then be right.
I would definitely recommend people to read them, in the order of their publishing, as internet speak changes fast enough to have a difference between 2019 and 2025.
My son would point out that the "incel cesspool" actually absorbed a lot of its vocabulary from 4chan and other "manosphere" spaces and there are a lot of people who talk that way who are not incels.
For instance that Clavicular guy who was profiled in the New York Times claims he is having sex and it seems he was actually "dating" a female influencer when he was being interviewed by an NYT reporter.
I know this is going to sound like an "old man yells at cloud" moment, but I cannot get over the number of people using "cause" as a replacement for "because."
Maybe it was my time spent in the book publishing industry, but it causes me pain every time I see it.

Something I have not seen discussed is the highly dynamic semantics of the annoying Gen Alpha variant of BrainRot. It has this fascinating aspect of slang with meanings that can shift in combination with other terms: Skibidi, Sigma, 6-7, Ohio -- Not only do these have flexible semantics in the first place, their meaning can dynamically change in the context of other such terms... if any meaning is intended at all.
As an example, "sigma" could be used as "He's so sigma!" (positive connotations) or "What the sigma!" (negative connotations) or "Sigma skibidi Ohio!" (what the sigma?!?)
And then there are suffixes like "maxxing" which seem straightforward ("bench-maxxing") but can be used in creative combinations, like somebody used "second-story-maxxing" to mean "going upstairs." Not quite Shakespeare, but funny.
I am no linguist but this seems unprecedented. At least ChatGPT thinks there is precedence, but only gave examples of nonsense terms in literature (like "The Jabberwocky") and counter-cultural slang or art (like Dadaism) or meanings that shifted over time.
However this idea of semi-defined words and memes that get combinatorially and dynamically redefined -- or even undefined -- seems different. I think this is more than just The Algorithm, it's more a spillover of a subculture into the mainstream. It's like slang that has intentionally internalized trolling and arbitrary word-coining as part of normal discourse.
