The 'OMG Secret Nazi' meme belongs to a niche category of internet humor centered around Pareidolia—the tendency to see meaningful patterns in random objects. It typically features a character reacting with exaggerated shock or horror to a shape, logo, or architectural layout that inadvertently resembles controversial iconography. While it originated in early forum culture and imageboards, it has evolved into a satirical way to mock over-the-top internet detectives who find 'hidden symbols' in everyday items. Today, it is used mostly in a lighthearted or ironic sense to point out design fails and unfortunate coincidences.
