How October 3 Became 'Mean Girls Day'—and How You Can Celebrate This Year

In 2005, Cady Heron correctly observed: "It's October 3rd." Since then, the day has been cemented in pop culture as 'Mean Girls Day.' Here's how October 3 came to be known as Mean Girls Day and the best ways to celebrate it.

How October 3 Became 'Mean Girls Day'

In the classic teen flick Mean Girls, a key scene sees Aaron Samuels (Jonathan Bennett) and Cady Heron (Lindsay Lohan) have an interaction in maths class.

Aaron turns around and asked Cady what day it is. In a voiceover, Cady recalls: "With Regina's blessing, I started talking to Aaron more and more. On October 3rd, he asked me what day it was. "

Their conversation then plays out, cutting to Aaron turning around in his chair and asking "What day is it."

Cady then excitedly responds: "It's October 3rd."

The conversation is seen as the beginning of Cady and Aaron's romance and the demise of Regina (Rachel McAdams) and Cady's friendship.

And just like that, October 3 has become known as 'Mean Girl's Day." For the past 17 years, fans have been celebrating their love for the iconic film on social media and with their friends.

How to Celebrate Mean Girls Day

1. Wear Pink

Mean Girls Day may not be falling on a Wednesday this year, but there is no better way to pay tribute to Mean Girls than wearing pink. It is Regina George's favorite color after all.

2. Buy Something Vintage

As Lea Edwards (Alisha Morrison) walked through the high school corridor, Regina stopped her in her tracks to 'compliment' her skirt. "I love your skirt. Where did you get it?"

"It was my mom's in the '80s" Lea replied "Vintage, so adorable" Regina replied before insulting the skirt.

Who could forget the cute tartan skirt Regina George described as the "ugliest effin skirt" she had ever seen?

Ignore what Regina said and channel your inner Lea Edwards by visiting a vintage store. You never know what you might find.

3. Watch 'Mean Girls' on Netflix

There is no better way to celebrate Mean Girls than by watchingthe movie itself and reliving all of the show's most iconic moments.

From "that's why her hair is so big, it's full of secrets" to "she doesn't even go here," relax and say your favorite quotes out loud by watching Mean Girls on Netflix.

The Mean Girls sequel is also available on the global streaming platform, but let's be honest, nothing beats the original.

4. Enjoy Happy Hour

Serve up some June George (Amy Poehler)-inspired cocktails to celebrate Mean Girls Day. Remember, Happy Hour runs from 4 p.m. to 7!

5. Practice for the Talent Show

Nobody can forget the Plastics' routine for the school talent show.

You may think it's a little early for Christmas songs but it's always the right time to perform "Jingle Bell Rock."

Alternatively, you could master Kevin G's (Rajiv Surendra) mathlete rap or blast some of Christina Aguilera's "Beautiful"—Damien's (Daniel Franzese) favorite song.

Here's an idea for your Halloween costume 2021: why not dress as the Plastics at Aaron's Halloween party.

You can take inspiration from Karen's (Amanda Seyfried) mouse (duh!?) costume, Regina's Playboy bunny gear or Gretchen Wiener's (Lacey Chabert) classy cat look.

Or you can channel Cady and go as Dracula's ex-bride. The choice is yours.
