Omegaverse, also known as
A/B/O (an abbreviation for "alpha/beta/omega"), is a
subgenre of
speculative erotic fiction, and originally a subgenre of erotic
slash fan fiction. Its premise is that a
dominance hierarchy exists in humans, which are divided into dominant "alphas", neutral "betas", and submissive "omegas".
[1] This hierarchy determines how people interact with one another in romantic, erotic and sexual contexts.
