I love the practice of requisitioning, remixing and reworking books, comics, movies etc. through any means you like, but I hate hate hate the way so much vocabulary that used to be rooted in individual creativity has been taken over by this kind of fucked up deference to mainstream publishing and ip.
easy example: everyone calls the characters they work up for their projects 'OCs' now. that genie is out of the bottle, I'm not even going to try and cram it back in. it's universal terminology. but I do want to reflect - why is the default position to assume that when someone says 'my characters' they mean something derivative, unless they specify 'my Original characters'?
similarly, all character relationships are 'ships'. but what's wrong with that? you say, it's just short for 'relationship'. and you would be right, by merit of completely ignoring the fandom ancestry and common understanding of that term in order to win an argument. because you know as well as I do that 'ships' aren't 'relationships', they're hypothetical romances that the speaker is rooting for. so why do I keep seeing people talk about shipping their OCs? why is a hypothetical relationship entertained and enjoyed by the creator of the work described using fan terminology?
I have for real no joke seen people talk about their 'headcanons' for their own characters, in their own stories. that's not a headcanon babe, that's canon!!! that's YOUR WORK. moreover, why are we even talking about the canonicity of your personal original writing? this isn't the star wars extended universe, why are international franchise IPs setting the baseline for the relationship you have with your writing and the terminology you use to conceptualise it?
tbc this is not a 'fandom brainrot' post. because I don't think it's fanwork that's the root of the problem. I think it's the insidious creep of capitalism and the ever more draconian weaponisation of copyright law that has rewritten our capacity for talking about creative work so that it revolves at all times around ownership and precedent. there is a deep learned anxiety about describing fictional works as fictional properties, that echoes in our vocabulary as we constantly make clear what is owned and what is not, what has been established on the record and what exists in the realm of speculation.
the reason 'fandom brainrot' is such a compeling stand-in for this issue is that it's really just one step downstream from all that voracious rent-seeking behaviour by publishers. if the only things you ever read or watch are in the milieu of those franchise copyright lawyers, that is the understanding of fiction-as-property you develop. if you're not exposed to a broader spectrum of art and artists, living and dead, who talk about their work as work - as expression, as experimentation, as a personal process and as a shared space with their audience - you will quickly be alienated from your own creative practice by design.
the point i want to make is this: going off the beaten track, exploring outside the franchises and bestsellers and box office babies, is not just a matter of good taste. imo it is a necessary act of solidarity with artists who still live, work and speak as individuals. it's a healthier environment for you as an artist. you deserve a relationship with your own work, not a ship.
