Sigma Boy is a 2024 Russian pop song by Betsy and Maria Yankovskaya that exploded on TikTok as the anthem of sigma and rizz memes, soundtracking confident edits and parody grindset videos. CupcakKe, the Chicago rapper behind a string of explicit viral hits, became a staple of shock-value meme audio in her own right. Fan-made mashups colliding the two circulate widely across meme pages and goofy ahh sound compilations, and this 12-second user upload is one such edit, kept alive by creators who love the clash.
