Alpha Beta Omega, where people have ‘second sexes’, alphas are basiclly memetic alpha males, omegas are subs that are claimed, and betas are the normal people who are probably keeping society running while everyone else loses their minds to magic sex hormones turning off their brains every five minutes.
It’s based off wildly inaccurate and outdated wolf pack dynamics and on Ao3 is largely an excuse to have a man who is strong and determined go through female style, often really rapey dynamics, while still trying to have them be the same character, somehow.

I’ve seen rare cases where it’s interesting, but in fanfiction… not so much.
