The phrase combines a long drawn out hey style call in Russian with blyat, a very common Russian swear word used for frustration, surprise or emphasis. Short clips like this circulate on user soundboards and in meme edits because the meaning is clear from tone alone, even for listeners who do not speak Russian. The recording sounds processed with a voice effect, which adds to its cartoonish feel. It stays popular as a quick reaction insert rather than as a quote from a specific film or show.
