There's this meme where a black cat says "А почему ваша бабушка меня "Свят-свят-свят" зовёт? Я же пушок.." I understand everything except the Svyat part (holy??). Could you please explain what this meme means? I feel a bit like a doofus.
“Свят-свят-свят: is indeed a short form of “Святой”, holy. Originally, it is a part of a Christian hymn (Sanctus), where a word “holy” repeats three times. Nowadays, Russian people use this phrase when English speaking people would use “Holy Jesus!” or similar words. It is rather a superstitious reaction on a black cat (bad omen), a sort of supernational protection :)
