I'm coming to deliver an official warning. The "Worst JoJo Ship?" post went WAAAAAAAAY too NSFW. All of that talk is against the rules. This is a warning. Contnued talk of such NSFW on the discussions post will lead to a ban. People don't need to have that sort of convo in public places.
So basically Sophia and Diavolo know each other irl and they were friends for a while. One day, Sophia made a trade on a game and Diavolo told her that it wasn't a good trade. Sophia got pissed and went like "Oh, I can't make any choices by myself. I suck. I'm trash.", and apparently Sophia said stuff like this for a long time. And Diavolo went like "Dude, you need some help" because Sophia kept on repeating these self-pitiful phrases, and Sophia got super pissed, so Diavolo cut their friendship because he was tired of Sophia's BS. And then they met on the same game, and Diavolo wanted some items she gave to Sophia returned to him, and Sophia said no so Diavolo jokingly called her a "scammer". Apparently, this got on Sophia's nerves, and now she started to post this on fandom, and Diavolo's scared because Sophia might spread rumors because they have mutual friends.
