The Grinch Poster Parodies originated from the marketing campaign for Illumination's 2018 animated film, 'The Grinch.' The original posters featured a close-up of the titular character looking smug or devious alongside relatable taglines about being grumpy during the holidays. Internet users quickly hijacked the simple, high-contrast aesthetic to create their own parodies, replacing the text with personal grievances, absurdist humor, or photoshopping the Grinch into other movie posters entirely. The meme effectively captures a sense of modern cynicism and petty annoyance, making it a staple for holiday-themed social media posts and 'anti-Christmas' sentiment worldwide.
