The story
- Russian · borrowed fromсу́ка блядь“fucking shit!”
- English todaycyka blyat
A partial orthographic borrowing from Russian су́ка блядь (súka bljadʹ, “fucking shit!”, literally “bitch whore”), compare cyka (“bitch”). It became common by the mid-2010s, first among online PC gamers, particularly European players of Counter-Strike: Global Offensive and Dota 2, because of the large number of Russian-speakers who play on European servers.
