Cheeki breeki is pretty popular. Or gopniks.

if everything is clear with gopniks, but what does it mean cheeki breeki? can you send me some kind of example?

Its a common meme based on the stalker game series. You can check the meme in google, but I highly recommend you listen to this. https://www.youtube.com/watch?v=BnTW6fZz-1E

woooow, it is very interesting! and in what cases this meme is appropriate?

as far as I know, anything Russian related. Its satirical.

Well, russian/slav people squatting while wearing Adidas clothing is pretty popular! So is saying/yelling "cyka blyat".

There's also yelling cyka blyat and saying "rush B", which is a fairly old Battlefield (I think?) meme, since many russians seem to play it, from what I've heard.

I think there was also a meme of Putin riding a bear a few years back? And that one drawing of Putin as a woman, which was apparently outlawed in Russia. At least that's what I've been told.

And, of course, the weirdest russian meme of them all: друг
knowyourmeme.com/memes/друг

ahahah ohh
I did not know about it(друг) like my Russian friends! very cool and scary

Definitely! It's based on the Deathclaws from Fallout - which are definitely one of the scariest creatures you can encounter in it, I think.

and what is a series of Fallout?

Oh, sorry! "Fallout" is a game franchise. It's set in a post-apocalypse America, in a mix of future and 50s.
