In Quebec French, people sometimes say of someone who’s not particularly bright:

“His mom rocked him/her too close to the wall.”

It’s just so… vivid and random.

“I piss in your mother’s death”

Alternatively, “May Stalin fuck you”

And yes, I live in Eastern Europe.

German: “Du Lappen”

Translates to “You rag”, pretty much calling someone a loser or idiot.

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.

baptême [ba.tae̯m]: “baptism”
câlice [kɑːlɪs] (calice): “chalice”
ciboire [si.bwɑːʁ]: “ciborium” or “pyx”, receptacles in which the host is stored
criss [kʁɪs] (Christ): “Christ”, or crisser, a more emphatic version of sacrer, both verbs meaning “to curse”
esti [əs.t͡si], [ɛs.t͡si] or ostie [ɔs.t͡si] (hostie): “host [cookie]”
maudit [moːd͡zi] (m) or maudite [moːd͡zit] (f): “damned” (or “damn”)
sacrament [sa.kʁa.mã] (sacrement): “Sacrament”
saint [sẽ]: “Saint”, added before others (ex. saint-simonaque, saint-sacrament, etc.)
simonaque [si.mɔ.nak] (simoniaque): from the sin of simony

viarge [vjaʁʒ] (vierge): “the Virgin Mary”
Moïse: Moses

Greetings from Poland.

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

كول هوا

“Kawl hawa”

Literally “eat air” in Arabic

Means shut up

“Spargeltarzan”, which is German for “asparagus Tarzan”. Basically someone who is physically weak, but tall and lanky.

I also like “Lauch”, which just translates to “leek”, the veggie. Oh, and “Bohnenstange”, which means bean stalk. We do seem to have quite a few vegetable-related insults in German, now that I think of it…

Triangeljosti.

The Jostiband is a Dutch orchestra for people with a developmental disability, mainly people with down syndrome.

A [triangle](https://en.wikipedia.org/wiki/Triangle_(musical_instrument\)) , or triangel in Dutch, is possibly the simplest instrument you can think of.

So calling someone a ‘triangeljosti’ is basically comparing them to someone who plays the simplest possible instrument in a band for developmentally disabled people.

In polish, calling people with the neutral gender. It’s a grave insult which implies lack of agency and dehumanisation, and thank to some rightwinger assholes in parliament is also a specific transphobic insult now.

While in english it’s completely normal thing to say if you’re not sure of a person’s gender.

So definitely not my “favourite”, i would never said this to anyone in polish and i occasionally get a hiccup of misgendering someone in english because of that, but interesting from language point of view.

Yiddish is not my native language but I think this one is so good it absolutely deserves a mention:

All of your teeth shall fall out except one that gives you a massive toothache.

German: “Dich soll der Blitz beim Scheißen treffen” - Lightning shall strike you while you’re taking a shit

Best insult ever, imo.

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.

My favorite has to be zkundyksicht, it comes from “z kundy ksicht” which literally means “a face [that came] from a cunt”. “Z” = from, “kunda” = cunt, “ksicht” = a rude way to say face.

In the dialect of the Italian province I’m from, my favorite insult is “Perdabàll”, which literally means “balls loser” as someone who’s so stupid and useless that could even manage to lose his testicles

Altough it’s more like a “gypsy curse”, but there’s one that translates to sth like “I wish you’ll having ten rings but none fingers”
