A playful combination of the names, Finn and Millie. It is a ship name given by fans for the teen actors, Finn Wolfhard and Millie Bobby Brown; who each played a key role in the show “Stranger Things.” It started off just when the first season aired and when their characters El (Millie) And Mike (Finn) had their first kiss. It was seen by some fans (mostly all the st fandom) that the two interacted well together in interviews, etc, like dancing at the premiere together, Millie calling him her ‘boyfriend on set’ and saying she ‘fell in love with his soul’.... this made fans to romantically fantasize about them as a couple.
