Skeletor first appeared as the main villain in Mattel's Masters of the Universe toy line in the early 1980s and became widely known through the 1983 He-Man and the Masters of the Universe cartoon. Bruh developed separately as casual slang for disbelief and was widely used in memes during the 2010s. Putting the slang in Skeletor's dramatic villain voice creates a deliberate anachronism, which is why the clip circulates in meme edits, reaction videos and soundboards as a short, character based alternative to a plain bruh reaction.
