The 'Toxic Yaoi' and 'Doomed Yaoi' tropes refer to a popular internet subculture that celebrates fictional male-male relationships characterized by unhealthy dynamics, obsession, or mutual destruction. While 'yaoi' is a long-standing genre, the 'Toxic' and 'Doomed' modifiers gained significant traction on platforms like Twitter and Tumblr in the early 2020s, particularly within fandoms like Chainsaw Man and Hannibal. These memes typically involve labeling two characters who are objectively 'bad for each other' with a specific 'Toxic Yaoi' stamp or banner. The humor lies in the self-aware romanticization of narratives that are tragic or dysfunctional, serving as a shorthand for fans to identify their favorite complicated and often heartbreaking character arcs.
