This kind of short hey chant is commonly used online as a vocal accent rather than as a standalone meme quote. It appears in music edits, gaming montages, sports clips, and fast reaction videos because the sound is brief, readable, and easy to place on a cut. Its continued use comes from that versatility: it can suggest crowd energy, a callout, or a mini burst of excitement without taking over the rest of the audio mix. Many creators treat it like a quick hype marker.
