The legendary 'HEYYEYAAEYAAAEYAEYAA' meme originates from a 2005 animation by Slackcircus, which re-edited footage from the 1983 animated series 'He-Man and the Masters of the Universe'. The clip features Prince Adam (voiced by John Erwin) and his alter-ego He-Man singing a high-pitched, upbeat cover of 'What's Up?' by 4 Non Blondes. In the most famous sequence, Prince Adam sings the chorus with a joyous, almost ecstatic expression while the backgrounds shift in psychedelic colors. This clip became a foundational pillar of internet culture, often used to represent pure, unadulterated happiness or 'vibing' through chaotic situations. It has evolved into a versatile reaction for moments of surreal triumph or when someone is feeling particularly fabulous. Example captions include: 'Me at 3 AM for no reason,' 'When the direct deposit finally hits,' and 'POV: You just finished your last final exam.'
