The Grinch meme originates from Dr. Seuss's beloved holiday character, primarily drawing from the 1966 animated special and Jim Carrey’s 2000 live-action performance. The most famous iteration features the Grinch’s slow, devious smile as he hatches a plan to steal Christmas from Whoville. This image became a quintessential reaction meme, used to represent mischievous intent, secret satisfaction at others' misfortune, or the joy of being antisocial. Whether it's the animated version's sinister grin or Jim Carrey's expressive facial contortions, the Grinch remains the ultimate symbol for holiday cynicism and relatable crankiness.
