The phrase Mein Führer is German for my leader and was used as a formal form of address for Adolf Hitler during the Third Reich. Because of that heavy historical association, short clips of the phrase have circulated online for years in parody edits, soundboards and meme compilations. Users isolate the address on its own, without a longer speech, so it works as a quick shorthand for blind obedience or overblown authority. It remains popular because the meaning is widely recognised even by viewers who do not speak German.
