PewDiePie is the online alias of Swedish creator Felix Kjellberg, whose comedy gaming videos built one of the largest audiences on YouTube. The big pp line grew from his recurring immature slang jokes aimed at his community, where pp is treated as a comic score or badge of honor rather than anything serious. Clips of the phrase were cut from streams and videos and shared on meme pages and soundboards, turning a throwaway reward line into a reusable reaction that fans drop whenever someone earns mock approval.
