It’s not an insult but a way to show frustration without hurling insults.
So here in Russian like
ЁКЛМНЭ
ЁПРСТ
Ёшкин кот
Блин (pancake) to not use Блядь (whore)
Мать твою за ногу
Пиздец
Ппц
hmm that’s all that comes to mind unless going into really insulting words.
In romanian I know only “Du-te in pula” “Du-te in pula mea” which is Get Fucked, fuck off.
Not for Lemmy precisely, but I said f it and never gone back(excluding random click). Trying to help AK community I was involved past few years. Moderating a bit on kbin AK magazine, but mostly either spend time on Discord where mix of reddit and non reddit sitting. Mastodon for more serious information and interaction with Lemmy, while Misskey for Arknights fanart/art with hopes that some federates to Kbin magazine(lately # not picking up sadly). Waiting for better mod tools, federation fixes.
