The exact origin of this chant is not documented in the details available for the clip, so it is best understood as an online voice meme rather than a scene from a known film or song. Its appeal comes from the repetition: Estel and echpochmak are easy to chant along with, and the stretched final yell gives editors a natural place to cut to a reaction. That simple, repeatable structure has helped it circulate as a short reaction sound, especially in playful videos where a loud, silly shout fits better than a polished line.
