Happy Mean Girls Day! Although Mean Girls premiered in theaters on April 30, 2004, fans celebrate the cult favorite on Oct. 3rd — the day that Aaron (Jonathan Bennett) asked Cady (Lindsay Lohan) what day it was and she replied, “It’s October 3rd.”

To celebrate, Mean Girls Day, Paramount uploaded the entire film to TikTok — in 23 parts. If you don’t feel like watching clip by clip, you can stream the film for free on Paramount+ and other platforms.

Coffee Mate also announced a Mean Girls-inspired, pink creamer on Tuesday (Oct. 3), but it doesn’t drop until next year.

For those unfamiliar with the plot, Mean Girls centers around a high schooler named Cady who moves back to the states after being home-schooled abroad and has trouble fitting in. At North Shore High, Cady gets a crash course in high school hierarchies and other shenanigans when the popular clique — a.k.a. the Plastics — invite her to sit with them.

Lohan, Rachel McAdams, Lacey Chabert, Amanda Seyfried, Lizzy Caplan and Bennett star in the film written by Tina Fey and inspired by the novel Queen Bees and Wannabes by Rosalind Wiseman.

In honor of “Mean Girl’s Day,” we rounded up all the ways you can watch and stream the movie, plus Halloween costumes inspired by the film.
