The line comes from God of War, released in 2018, where Kratos constantly addresses his son Atreus simply as Boy instead of using his name. Players quickly noticed how often the word appears during exploration, puzzles and combat tutorials, and clips began circulating on YouTube and social media soon after launch. It turned into a shorthand meme for strict parenting and mentor frustration, remixed into other games and videos, and it remains closely tied to this softer, older version of Kratos.
