The Jim Carrey Turning Into The Grinch meme features a series of stills from a behind-the-scenes interview where Carrey demonstrates his incredible facial elasticity by recreating the Grinch's signature malicious grin without any prosthetic makeup. The meme typically follows a progression where a person starts out neutral and slowly adopts a sinister or mischievous expression as they realize they have the upper hand or a devious idea. It is widely used to represent relatable moments of pettiness, 'villain eras,' or when someone finally thinks of the perfect, albeit slightly mean, retort during an argument.
