CG5, also known as Charlie Green, is a popular YouTuber and musician who gained massive fame by creating high-quality songs based on internet culture, viral trends, and video games like Among Us and Five Nights at Freddy's. However, he eventually became a meme himself through the 'CG5 Curse' or 'CG5 Effect'—a community-driven running joke suggesting that once he creates a song about a trending meme, that meme is officially 'dead' or has reached peak saturation. This irony-fueled trend often features clips of CG5 dancing or singing from his high-energy music videos, used to signal the end of a meme's lifecycle or to poke fun at his speed in capitalizing on digital trends.
