PewDiePie, real name Felix Kjellberg, became one of YouTube's most-subscribed creators through gaming commentary and meme culture in the 2010s. The triangle became a recurring community joke after viewers kept spotting the shape in his videos and joking about Illuminati confirmation, which he played up on camera. Clips of the gag were ripped, remixed and shared across meme pages and soundboards. It endures because it is short, recognizable and flexible, working as shorthand for mock conspiracy humor without needing context.
