The phrase is Portuguese for Satanas is my lord, and the clip circulates online as a short shock humor soundbite rather than a sourced quote from a known film or show.

Creators reuse it in meme compilations, gaming edits and reaction videos whenever a character embraces evil, power or chaos in an exaggerated way, keeping the two second shout in regular rotation.
