Hikakin and Seikin are Japanese YouTube creators and brothers known for high-energy music, beatboxing, and entertainment videos, and the word call in the title reflects the Japanese term for a crowd chant or response. Short clips from their work circulate online as recognisable audio memes, especially among fans who follow Japanese creator culture. This excerpt is used less as a full song and more as a compact signature moment, which is why it works well in short-form edits, reaction videos, and fan compilations that want an immediate, familiar Japanese pop-culture reference.
