The tune comes from a performance by Soviet baritone Eduard Khil, whose wordless vocalise replaced the original lyrics and became known online simply as Trololo. A clip of his cheerful, old television performance spread on YouTube around 2009 and 2010, turning Khil into an unlikely internet star nicknamed the Trololo Man. The meme endured because the melody is instantly recognisable even without words, and its happy, oblivious tone makes it perfect for trolling, ironic celebrations and light-hearted mockery in short-form video today.
