Băga-mi-aș pula-n coliva mă-tii de să-mi sară coaiele din bomboană-n bomboană

This is a highly niche one in my native language as well, as one must also know what is colivă - it’s basically a desert that we eat at funerals with m&m-sized candies in it as well. So it roughly translates let me stick my dick in your mother’s coliva so hard that my balls jump from candy to candy

My personal favourites from Finnish.

“Ei ole kaikki muumit Muumilaaksossa” “Not having all the Moomins in Moomin Valley” Used for people who are either stupid or lack sanity. There are other variants of this and Moomin one is not older than a couple of decades.

I find our version of Grammar Nazi pretty great. We call them comma fuckers.

“Ei voi kauhalla ottaa jos on lusikalla annettu” “You can’t take with a ladle if it was given with a spoon”. This refers also to a lack of something, usually a lack of intelligence or sense.

Swedish Skitstövel - shit boot, basically means asshole

Very Belgian: He doesn’t have all his fries in the same bag / Il n’a pas toutes ses frites dans le même sachet

Meaning that he’s/she’s dumb or confused :D

Brazilian portuguese tends to lack impactful phrases, but is full of single curse words. A big portion of them a clear example of how much negative bias there is culturally against certain groups (gay men, women in general, disabled), unfortunately :/

One that isn’t often used, but that I almost always laugh loud whenever I hear, is “Enfia uma dentadura no cu e sorria pro caralho”, which roughly translates into “Stick a denture up your asshole and smile at the dick”. For when simply saying “go fuck yourself” isn’t enough.

Probably “sluta vara en så lagom rolig person”. It isn’t directly an insult. However, it’s not something you would love to hear. It translates to “stop being a person who has the just right amount of fun”.

Another thing my friends say when they are med is: “Din jävla ångvält!” which translates to “You fucking steamroller!”.
It just sounds much better in Swedish.

All of our swear words are Catholic church vocabulary words. As a never Catholic I always find them hilarious when I say them. They can basically be used as stand-ins for words in the same way as we use “fuck” in English or strung together.

“Saint Ciboire” was my grandmother’s favorite when I would fuck something up.

Du hast doch nicht alle Tassen im Schrank - German, you don’t have all your cups in the drawer.

Telling someone he is stupid via comparison to cups. Why? Who knows.

“mange tes morts” in french, can be translated to “eat your deads” which is like go fuck yourself

In Tamil: சோத்துல உப்பு போட்டு தான தின்ற?

Translation: Don’t you add salt to your food?

Context: This is when somebody doesn’t react/listen/change no matter how much they are insulted. The other party asks if they add salt to their food, or if they only eat bland food, and thus have lost all emotions and have become as bland as their food.

It’s a bit difficult to explain, but the general belief is that food reflects your emotions and reactance and moods. Bland food - emotionless, spicy food - easy to anger, etc.

Word: Muji

In Devnagari (Nepali): मुजी

Meaning: A woman’s pubic hair

In sentence: तँ मुजीको गाला फुट्नेगरी पड्काउॅछु।

Translation: I’ll slap the living crap out of you muji.

Greetings from Poland.

“bambaryła” - someone who is very silly. Also: someone who is very fat. A little old-fashioned.

German Korinthenkacker (currant shitter) is someone who tries to win an argument by looking at unimportant details.

Alternatively, “May Stalin fuck you”

And yes, I live in Eastern Europe.
