October 3 has been dubbed on social media as "Mean Girls Day" in reference to a quote said by the film's main character Cady. People also celebrate by wearing pink based on another quote said by character Karen in the film. Clothing designers have followed suit by printing quotes and other iconic imagery from the movie onto many pieces and merchandise items. Due to the recognition and attention generated because of the annual celebration, several members of the cast have reunited in video over the years on that day for various causes. In 2017, they set a GoFundMe to raise money for the victims of the Las Vegas shooting and the National Compassion Fund. In 2019, they teamed up with the Thirst Project to raise money to fund a freshwater well in Uganda. In 2020, the cast was honored with the Pioneering Spirit Award for their #MeanGirlsDoGood campaign. On October 3, 2020, Katie Couric moderated a virtual cast reunion to reminisce about the film. Organized in collaboration with HeadCount to promote voting in the 2020 United States presidential election, it was the first time the entire cast gathered together since the premiere in 2004.
