I sometimes find myself confused by how many weird concepts and phrases get used commonly on this site, especially ones that are either internet-specific or scholarly in origin, so I thought just for fun I'd try to draft up a cheat-sheet of some of those terms I've seen used here a lot and let other people help with what I've missed. I figured this may be good as a refresher or a way to learn new ones. Here we go!
Bechdel-Wallace Test (commonly called the Bechdel Test): a frequently-used "lowest bar" for representation of women in a work of fiction, where a passing work must include two woman characters that have a conversation that isn't about a man. Developed as a joke by Liz Wallace and Alison Bechdel as a criticism for the lack of lesbian representation in cinema
Bidoof's Law: states that the kinds of guys that make insane posts about moral degeneracy on social media are often "openly and shamelessly addicted to hentai". Named for infamous tumblr user 'bidoof', who hopefully won't find this post
Chekhov's Gun: literary trope that suggests that one should not draw attention to specific details unless those details will be important to the story; the original example was that a play featuring a gun on a mantle in the first act must have that gun fired by the final act. Named for Anton Chekhov, who is not the guy from Star Trek

Enshittification: economic pattern where companies (particularly ones in the tech sector) provide an excellent service at a loss in order to gather a userbase, then gradually worsen their product to attempt to gain a profit, all while hoping the userbase will continue using the service out of familiarity; inevitably, this results in the service's abandonment and death. Coined by Cory Doctorow
Godwin's Law: joke theorem that suggests that the longer an internet argument goes on, the more likely someone will mention the Nazis. Internet tradition typically follows the belief that, should an heated debate result in someone comparing the other party to a Nazi, and the debate otherwise has absolutely nothing to do with Nazis/fascism, that person has lost the debate entirely. Coined by Mike Godwin
