The greatest expression of love is joining someone else's fandom.
Just think about it for a while. First you have to consume the media the fandom is based off of, and while it's possible for it to just be one book or one movie, it's almost always a series. A lot of times there a book AND movie series.
But that isn't nearly enough. Having read or watched the Maze Runner doesn't mean you get the page 250 jokes. Reading Percy Jackson doesn't mean understanding "you drool in your sleep" and "you're not my type" (this one especially now with the casting for the series).
Also. We notice a ridiculous amount of breadcrumbs to defend any point possible (I've seen a PowerPoint presentation on Tumblr as to why the Gladers should say fuck).
And the amount of weird ship names is just ridiculous (there may be a reasonable justification, but wolfstar and rosekiller are just not intuitive), as well as random fixations on completely unimportant characters.
Here's a list of ones I can think of off the top of my head:
Evan Rosier, Barty Crouch Jr., Regulus Black, Pandora [last name unknown], Blaise (I forget the spelling) Zabini, Crabbe, Goyle, and Pansy Parkinson for Harry Potter. Ben, Nick, George, Stephen, Sonya, Harriet, and Rachel for the Maze Runner. Ethan Nakamura (I think he's more important but I can't remember), Kayla Knowles, Austin Lake, and Lee Fletcher for Percy Jackson.
If you just read the books once, you probably don't notice most of these characters.
Just in general there's so many inside jokes and references and quotes and concepts and fanon and headcanons, and all of it is would be so exhausting to keep up with if you weren't completely invested in this made up world some random person came up with.
