There is not enough reliable source information attached to this upload to confirm where MJ originally comes from. The clip appears on soundboards as a short standalone reaction audio, which is common for meme sounds that spread faster than their credits. In practice, creators keep using it because brief, vaguely titled clips are easy to repurpose across edits, compilations, and joke reactions. Its staying power comes less from a known backstory and more from how adaptable the sound feels when paired with sudden visual changes or punchlines.
