The sound comes from 'Sigma Boy', a 2024 Russian pop song by the young singers Betsy and Mария Янковская, released that October. A catchy chorus praising a confident boy turned it into a TikTok phenomenon by the end of the year, with millions of edits, dances and lip-syncs spreading it far beyond Russia. It rode the wider 'sigma' meme mocking alpha-male posturing, so it works both as hype and parody. Like the spiderman meme song, it shows how a short musical hook can dominate short-form video.
