“Muh Holocaust” is an anti-Semitic meme invented by white supremacists to depict Jews as “whining” about the Holocaust, particularly when confronted with ostensible criticism.
The word “muh” in the phrase stands for the word “my.” The phrase evolved from a broader meme on forums such as 4chan depicting people of different backgrounds or political persuasions spouting off on various subjects—with the rants simply replaced with the shorthand phrase “Muh X,” as in “Muh heritage,” “Muh freedoms,” “Muh guns,” etc.
White supremacists quickly appropriated the meme for anti-Semitic purposes, making “Muh Holocaust” one of the most popular of the “Muh” memes. The phrase has become shorthand for the anti-Semitic claim that Jews routinely use the Holocaust to deflect attention from any unwelcome subject, or simply to gain attention.
In graphic images, the phrase “Muh Holocaust” is often combined with use of the Happy Merchant cartoon.
