The Haha Yes Hedgehog meme features a small, ceramic or toy hedgehog figurine, often depicted in a sink or looking directly at the camera with a look of quiet triumph. It is traditionally accompanied by the simple, affirmative caption 'Haha Yes.' The meme gained significant traction on platforms like Tumblr and Twitter, becoming a shorthand for smug satisfaction or simple agreement. Its popularity exploded globally when Elon Musk tweeted the image in late 2017, cementing its status as a go-to reaction for tech enthusiasts and casual internet users alike. Today, it is used to celebrate minor victories, acknowledge clever solutions, or simply express a state of prickly contentment.
