The exact origin of this 'ra ra ra ra' clip is not documented, which is common for short user-uploaded soundboard audio. It circulates as a tiny, loopable vocal hook rather than a quote from a known show, film or song. Because it is only about two seconds long and purely rhythmic, editors treat it like a verbal drum fill. Its continued use comes down to utility: it is short enough to fit anywhere, catchy enough to stick, and neutral enough to work over gaming, comedy and hype edits.
