Listed online as LaughKing.SIV, this clip circulates on user generated soundboards as a short reaction laugh with no clear credited source in its listing. Its appeal comes from the exaggerated, royal sounding delivery rather than a specific quote or scene, so creators reuse it across unrelated videos. It fits the wider family of evil laugh and cartoon laugh sounds shared for memes, including the woody woodpecker laugh, and it stays popular because the long, confident cackle instantly signals a character thinks he has won.
