The He-Man Sings meme, famously known as HEYYEYAAEYAAAEYAEYAA, originated from a 2005 flash animation created by the duo Slackcircus. The video features Prince Adam and characters from He-Man and the Masters of the Universe lip-syncing to a high-energy dance remix of the 4 Non Blondes song What's Up?. Its surreal neon visuals, campy animation, and infectious joy turned it into an early YouTube masterpiece. The meme is frequently used to express unbridled excitement, chaotic energy, or as a vibrant alternative to the Rickroll. It remains a definitive pillar of internet culture, celebrated for its absurd humor and nostalgic 1980s aesthetic.
