The 'Human, I Remember You're Genocides' meme originated as a parody of poorly written Undertale fan games and edgy 'creepypasta' mods. In these mods, Sans often confronts the player about their past sins in the Genocide route using overly dramatic dialogue. The meme gained viral status on platforms like Reddit and Twitter due to the intentional grammatical error 'you're genocides' instead of 'your genocides.' It has since evolved into a staple of 'brainrot' humor, where the nonsensical phrase is paired with distorted images of Sans or other characters to mock the absurdity of overly serious fan content.
