The 'Based on What?' meme revolves around the intentional or accidental misinterpretation of the internet slang term 'Based,' which signifies authenticity or speaking one's truth. While younger internet users use the word as a standalone adjective, the meme portrays a literal-minded or older individual—often depicted as a confused grandfather or a stern character—demanding to know the source or foundation of the claim. It first gained traction on platforms like Twitter and 4chan as a way to mock those out of touch with modern digital dialect. Today, it serves as a versatile template for highlighting the absurdity of internet lingo and the awkwardness of cross-generational communication.
