October 3rd: Mean Girls Day

Mean Girls (2004)

For fans of the cult classic Mean Girls, October 3 is celebrated as Mean Girls Day.

Deep Dive

  • The date comes from the movie scene where Cady’s crush asks, “What day is it?” and she answers, “It’s October 3.”

  • Fans mark the day by quoting the film, sharing memes, and rewatching the movie. If you are short on time, Ariana Grande’s thank u, next video includes a quick tribute with several iconic moments.

  • Pink is the unofficial dress code. It nods to the Plastics’ rule: “On Wednesdays we wear pink.” When October 3 lands on a Wednesday, the holiday feels extra on theme.

How people celebrate

  • Wear pink and post a selfie with a favorite quote

  • Host or join a group watch party online or IRL

  • Share Burn Book style memes, “you can’t sit with us” jokes, and fetch references
