Yaoisexuals are straight girls who fetishize mlm (men who love men) relationships. They will frequently watch animes or consume other forms of media in which two men are in love, and will try to label the men in the media as their "little gay sin babies". Another way to describe straight girls who identify as yaoisexuals is fujoshi.
Person 1: Did you hear? Allison is yaoisexual.
Person 2: Isn't that just a fancy way of saying straight girl who fetishize gay men?
Person 1: Yeah it is.
Person 2: That's fucking disgusting, thanks for letting me know. I'm gonna go drop kick her right now.
