Groypers, sometimes called the Groyper Army, are a group of alt-right, white nationalist, and Christian nationalist 41 activists led by Nick Fuentes. Groypers are a loosely defined group of Fuentes’s followers and fans. They are named after a cartoon amphibian named “Groyper”, a variant of the Internet meme Pepe the Frog.
