Blyat is a common Russian swear word, and the paired phrase suka blyat became a familiar outburst in online gaming culture long before short soundboard clips circulated. English-speaking players picked it up from voice chat, streams and rage compilations, where Russian-speaking gamers used it during deaths, missed shots and bad luck. Shortened angry versions like this one spread as a universal rage reaction, used even by people who speak no Russian because the tone alone makes the meaning completely clear.
