The movie is about a new girl in a high school dominated by a clique of popular girls called "The Plastics," consisting of Regina George, Gretchen Wieners, and Karen Smith. The story follows Cady Heron, played by Lindsay Lohan, as she navigates the social hierarchy of high school and becomes friends with The Plastics, only to turn against them.

It addresses the issue of girl-on-girl cattiness and the impact of alpha girls on everyone else. Mean Girls has become a pop culture phenomenon, with fans making GIFs and memes of the film and posting them on various social media platforms. It is considered one of the most quotable movies of all time.
