Not my circus, not my monkeys. (English)

It's me sausage actually. And it doesn't mean no fucks given, rather it is all the same to me.

Turkish: Not on my cock (Sikimde değil)

What are they doing in the Netherlands?

This is missing the worst one to translate:

I have kama two.

It doesn't fully make grammatical sense in the original Estonian form either. The "have" part is also usually skipped, leaving just the noun case implying ownership over the kama

This is just one of many ways to say it in Estonian. We really are a nonfuckgiving people, except when we give too many of course. You can also say "I have clay" or "I have a (violin) bow". Of course these are just slightly rude (depending on tone and conversational partner), you can also say "doesn't ballsack me".

Ma doare in pulă. That is in romanian from what I have learned which basically means I feel pain in my dick

"I have it up my ass" (Polish).

There are more vulgar ones in Spain:

Me la suda ("la" refers to "la polla"): It makes my dick sweat

Me la pela: It peels my dick

Me importa una mierda: That matters a shit to me

Obviously, this last one is closer to "I don't give a shit," but it's essentially the same sentiment.

n. I couldn't give a flying fuck (English English)
n+1. Ah couldnae gi a flyin' fuck (Scottish)

Rare french w

I Brazilian portuguese that would be "Caguei" -> I took a shit

Swearing in Greece and across most of the whole region is hilarious. The actual "I don't care"/"zero fucks given" phrase is to write something on your balls or dick.

So many sayings are mother/whore/balls/dick based - not offensive phrases, just common sayings.

My dick hurts (Bosnian, Serbian, Croatian)

Geez, the Greeks are a surly bunch.

It sucks me (as in fellatio) an egg (testicle).

It sucks my dick.

I care a crow's nest (as in ships)

I care a turd.

I care a shit.

(Spanish again, we are creative people, as someone pointed out, the New World is way more colorful than Spain)

It naps on my dick. (Bulgaria)

"I shit on it!" ("Szarok rá!") - in Hungarian.

Besides that just "I don't care." ("Nem érdekel.")

Maybe "Not even the dog cares, who lives in/at the shooting range." ("Lőtéri kutyát nem érdekli.") But it's more like for situations where you want to express, that nobody cares.

It cares me dick. (Spanish)

Nr. 2 is awkward for people wanting to use manure on plants...

Somehow, the German and Spanish versions just aren't vulgar enough.
