Originating from the French gaming forum Jeuxvideo.com—specifically the infamous 15-18 board—Noelisme is a massive internet subculture centered around the :noel: smiley. Emerging in the mid-2000s, it represents a unique brand of absurdist humor, forum raids, and a distinct vocabulary including legendary phrases like 'Onche' and 'Panachay.' The movement was famously defined by its rivalry with 'Hapisme' (the :hap: smiley). While its peak influence occurred in the late 2000s and early 2010s, Noelisme remains a cornerstone of French web history, symbolizing the chaotic, creative, and community-driven energy of early message boards.
