Little is documented about where this recording first came from, so its history is mainly in how the phrase travels online. Pantsu nugitai is plain Japanese for wanting to remove your pants, and that simple, slightly embarrassing meaning needs no backstory to understand. Short Japanese voice lines like this are often clipped, shared on soundboards and reused as reaction audio, because viewers who do not speak the language still grasp the tone once they learn the translation. Its appeal stays in that instant, out of place honesty.
