The 'Is It Porn?' meme template revolves around the humorous ambiguity of certain images that, at first glance, appear to be NSFW but are actually innocent objects or scenes. It draws inspiration from the 'Is It Porn or...?' series of optical illusions that circulated on social media and early internet forums like 4chan and Reddit. The meme is typically used to highlight the internet's collective tendency to see suggestive imagery everywhere or to poke fun at misleading thumbnails. Users often apply this template to zoom-in shots of knees, elbows, or everyday household items that possess unfortunate shapes, questioning the viewer's perception and 'dirty' thinking.
