when someone walks into a room where you are playing piano and they are very surprised to see you playing the piano
….so like. there’s fanfic for south park? good fanfic? because. um. if you have secret knowledge you wanna share, please feel free.
There is actually a pretty substantial South Park fandom (including a shockingly large wealth of Japanese fanart for the show) so uh, yeah, there… is… a lot of fic, at least. But I could not in good conscience recommend for anyone to go in there. My brief flirtations with the fandom back in High School were mostly the of “morbid fascination” “holy shit this exists" variety and I honestly don’t think it’s gotten much better since then. It’s a very… earnest and well meaning fandom, but almost everything I’ve ever seen of it just gives me mad embarrassment squick with a hearty side-dish of “I wish I could unsee”. So. No. No there isn’t good fanfic.
I like being charitable, however, so idk, your mileage may vary??? South Park just isn’t the kind of thing I’ve personally felt I needed a fic fandom for???
Esp. not for Kyle/Cartman
Sorry I could not be of more assistance.
