The sound comes from the He-Man sings meme, built around What's Up by 4 Non Blondes and Prince Adam belting out the hey chorus. A fan edit commonly known as Fabulous Secret Powers spread the joke online in the mid 2000s and it later exploded again on YouTube and in meme edits. The exaggerated singing became shorthand for flamboyant confidence and campy joy. Shorter cuts now circulate on soundboards, while this longer version keeps the full build that made the original clip so recognisable.
About this sound
The I Say Heyeyeyey sound is the stretched He-Man What's Going On singing meme, used for goofy reveals, singalongs and absurd reaction edits.
This clip stretches out the famous hey chorus into a long, wobbly singalong that keeps rising and falling for almost half a minute. The voice is deliberately over the top, bright and theatrical, turning a simple greeting into a full performance. It sounds cheerful at first, then increasingly ridiculous as the notes drag on and on. Viewers recognise the energy instantly, which makes the moment land as a joke before anything else happens. It works because the singing is sincere, loud and completely mismatched with most ordinary scenes.
