Sigma Boy is a Russian pop song by Betsy and Maria Yankovskaya, released in 2024 and turned into a global TikTok hit in late 2024 and 2025. Its catchy chorus became shorthand for the internet sigma meme, celebrating exaggerated confidence and lone-wolf characters. Slowed and slow-motion edits soon followed on TikTok and YouTube Shorts, where creators stretched the track to make entrances feel heavier and more dramatic. That slowed style stuck because it keeps the hook instantly recognisable while changing its tone completely.
