Online, 'тыщ' circulates as a short slang snippet rather than a quote from a known show, film or character, and no verified source has been attached to this particular recording. In Russian-speaking meme culture the word itself is everyday shorthand for 'a thousand,' often tossed into jokes about money, salaries and absurdly high numbers. Creators picked it up as a reusable reaction sound because the clipped delivery fits quick cuts, and its popularity comes from that versatility rather than any single viral video.
