The sound comes from a 2021 TikTok freestyle by Florida twins Flyysoulja and Kodiyakredd, who filmed themselves singing in a pool about being island boys. The clip spread far beyond their account after viewers shared it as an unintentionally catchy and awkward performance, sparking duets, parodies and remixes across TikTok. Their look, slang spelling of boi and repeated hook turned the phrase into shorthand for a laid-back island persona. It remains a familiar meme reference for carefree confidence, beach styling and performances that are memorable despite being rough around the edges.
