Originating from supernatural fandoms around 2010, the Omegaverse (or ABO) is a subgenre of fan fiction that establishes a biological hierarchy among humans based on canine social structures. It features distinct roles—Alphas, Betas, and Omegas—often involving themes of heat cycles, pheromones, and soul bonds. The genre became a massive internet phenomenon and a source of endless memes due to its surreal complexity and a high-profile legal battle involving author Addison Cain and YouTuber Lindsay Ellis. Today, it is used in memes to represent the 'rabbit hole' of internet subcultures or the sheer confusion of explaining niche tropes to the uninitiated.
