The 'Prank Him John' meme originated from a viral short-form video where a group of friends captures a sleeping individual, leading to the iconic command 'Prank him, John.' Instead of a mild joke, the 'prank' is usually depicted as an absurdly aggressive or high-impact action, often punctuated by the responder's line 'You already know.' It gained massive traction on platforms like TikTok and YouTube through various 'sus' edits and sound-effect remixes. Today, it is widely used to describe situations where someone is about to be completely overwhelmed or 'clapped' in a competitive gaming or social setting.
