Yep. What they saying is "parashka", a russian meme. It's made from words "parasha" (type of toilet used in prison cells) and rashka (which is "russia" (not Rossia, exactly the English pronounciaton) with part "-ka" which has very wide use in Russian). The word is written in hieroglyph-like font to make it look like the original "Yukkuri shiteite ne".
And yes, it is used by xenopatriots to refer to Russia and to express their despise to it. Typical sentence with this word is "shitty parashka became shitty shit" (actually, in Russian this sentence contain "shit" only once. It's more like "crappy parashka became crappy shit", but the word "sraniy" used as "crappy" literally means "the thing that has been shit"; srat' is a...uhm...i forgot the English word for a word which describes process. which means "to shit".
