Same. I'll take a stab at it without doing any research.

I'm guessing Clavicular is a person, perhaps an influencer. I believe the implication is that the old crone he rated as a 4/10 was a witch who cursed him to wake up without a jaw because that would be ironic given his name.

How'd I do?

I needed help understanding this brave new world, and this breakdown by ABitFruity really helped:

A longform leftist discussion on Clavicular: Clavicular Is a Symptom, Not The Cause (with F.D Signifier and Kat Tenbarge)

The TLDR: Clavicular correctly identifies a real issue that we on the left have identified for decades, that society and people within society are implicitly biased towards a social definition of beauty, which Clavicular identifies as the "floor" of your potential. No matter how good you are at something, if there is a more beautiful person as good (or even less good) at the same thing, society will pick the "more beautiful" over the more capable every time. Literally, Claviculars analysis is the same critical analysis that results in policies like DEI, to try and undo some of this implicit bias that society has artificially baked in. Its just that their response isn't to try and change or rage against that implicit bias, its to try and work within it, ie, look-maxing, to become the most beautiful person, so you start at the highest implicit social rung.

Just watch two minutes of this clip. It captures the whole point: https://inv.nadeko.net/pvqBPkJIkmc?t=4693

There-in lies the humor. Don't ever learn the lingo, just start subtly mentioning cortisol levels to give young people in your life aneurisms. It's great.
