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.
