Nick is one of the four survivors in Left 4 Dead 2, Valve's zombie shooter released in 2009, and his in-game shouts are clipped for memes because they sound sharp and confrontational out of context. Russian-speaking editors paired one of those shouts with slysh ty kozel, a blunt insult that works as a roast, and then applied the bass-boosted treatment common to loud meme edits on YouTube and TikTok. The result travels well because it needs no translation to feel aggressive, and it shows up in gaming compilations and short-form edits where a sudden insult is the joke.
