Selfcest

And this is where selfcest comes in. For those unfamiliar with Adventure Time, it has two series: the main, phallogocentric one, Adventure Time, and another spin-off version, Adventure Time: Fionna and Cake, in which gender-flipped versions of the original characters are presented. Marceline spawns Marshall Lee, Jake turns into Cake, Finn becomes Fionna, Princess Bubblegum is chewed up and spat out as Prince Gumball… you get the picture. Enter Fanfiction, which causes them to hook up. Creepy, yes.

Several Loki fans shared their horror over the idea of Loki and Sylvie getting together, as it would be an example of selfcest.

'"The Time Traveler's Wife” having selfcest was not on my 2022 bingo card,' another [Twitter] user commented.
