This sound is tied to the Scavs from Escape from Tarkov, the hardcore extraction shooter developed by Battlestate Games. Short Scav voice lines became widely shared in clips, compilations, and gaming memes because they instantly identify the game’s hostile NPCs and their unpredictable fights. “Cheeki Breeki” was already familiar online from Russian gaming culture, which helped the phrase spread even further among shooter fans. It is still popular because one quick line can turn a normal death, rat encounter, or loot panic into an instantly recognizable Tarkov joke.
