As native Russian speaker, this is terribly rarely used in this full format (and it's one among many), but genuine, I've heard it IRL.

"Тебя не ебёт, так не подмахивай"

This is highly and universally derogatory, you could expect to hear it from lowlife/criminal, which, unfortunately, is what most russians are lately, though. For russian nazi population, this implies that you are gay or a slut, depending on biological sex, and that's close to your life worth nothing. For the rest, this is just something nazies would say to insult you.

The first part alone, though, is quite socially acceptable and overused. I guess, because it's lost the whole lore behind it, and showing your knowledge of whence it came from kind of reveals that it's not just an empty word, but you mean it.

I'm a bit hyperfocused on swearing, am I? Was one of my childhood's special interests.

Honestly, "mind your beeswax" is also a rare gem, but not quite so rare.

Chilean Spanish? that's just a common Spanish saying

I've always been partial to "This is an A -- B conversation, so C your way out."

Australia: Nunya

The Scouse British dialect has a nice term for this: "Geg out". As opposed to "Fred is gegging in", used when someone is trying to implicate themselves or become part of the group/conversation.
Someone involving themselves when they shouldn't be? Two syllables: Geg. Out.
No idea where it comes from but I heard it a lot in my youth. Forsomereason.

In Denmark, the youngsters have recently been saying "spurgt?" which translates to "asked?" - as in "were you asked?". Somehow the brevity and linguistic lazyness makes it even more infuriating.

I will wiggle by ass on the camel & make signals with my candle whilst lubricating my onions with beeswax for you to fuck as I please, ok?!?!!

It's not a "no one asked you", but it is an idiom. As you can probably guess, it means more "don't help people working against your interests".

So, you'd say something like that to a pro-ICE minority person, for example.

In English it’s: Nobody asked you!

Apparently the Argentine equivalent is something like “take your hat off, you’re not in this photo”

(Ireland) Wind yer neck in

Another reason to love Russian (the language).

In Taiwan it's “關你屁事“

Which is mildly translated to "Care about your fart situation"

This is pretty derogatory. I wouldn't use it unless it's with your friends messing around.

Qué te importa. Come torta. Con tu hermana la gordota.
