Gayus ex Machina

In works of fiction; the use/revelation of a character’s sexuality to advance the plot. Similar to Deus ex Machina, but gayer.

Girl 1: “Omg, Madonna was literally dying till she realised she was actually in love with Shakira, then she got up and started dancing! That’s the power of love for you.”

Girl 2: “No, that’s the power of Gayus ex Machina and bad storytelling.”
