Garen is one of the original champions in League of Legends, released in 2009, and his habit of waiting hidden in brush became a long running joke in the community. Because brush blocks vision until you step inside, an unseen Garen could burst out at close range with almost no warning. Players turned that shared experience into memes, clips and soundboard posts about facechecking, and the gag still works because the setup needs no explanation for anyone familiar with the game or similar MOBA ambushes.
