Chto blyat is a common Russian profanity built from the words for what and a strong swear word, long used in everyday speech before it became an isolated meme clip. Shortened to just this shouted phrase, it spread through gaming clips, reaction edits and soundboards where language is no barrier to tone. Viewers who do not speak Russian still read the anger and disbelief instantly, which helped the sound sit alongside other short reaction staples like the bruh sound in creator libraries.
