On October 3 at North Shore High School Aaron Samuels asked Cady Heron what day it was. She responded: "It's October third." And a national holiday was born. If this is all very confusing then you clearly need to brush up on your recent cinematic history. Mean Girls is an inimitably quotable 2004 comedy written by Tina Fey and starring Lindsay Lohan. The movie follows Lohan as Heron, the new girl at an Illinois high school who falls in with queen bee Regina George and her clique, "The Plastics." For its fans, the movie is dear not only because it is hilarious, but also because it rings so true for anyone who has had the experience of being an adolescent female. It deserves to be celebrated.

Of course, Mean Girls Day is big on Twitter, where hashtags like #NationalMeanGirlsDay and #meangtweets are going strong. An account attributed to "Regina George," played in the movie by Rachel McAdams, reminded users that this year's Mean Girls Day is a special one because it falls on a Wednesday, and on Wednesdays the Plastics wear pink. 

Tomorrow, National Mean Girls day falls on a Wednesday. This won't happen for another 6 years... WEAR PINK OR DIE. #NationalMeanGirlsDay

As of publication the tweet from "Regina" has been retweeted over 18,900 times. For further reference:

There's also this gem from an account dedicated to Lindsay Lohan fan fiction: 

BREAKING: Lindsay is being arrested outside a NYC Taco Bell for throwing her phone at a young fan who asked her 'what day it was.'

The Obama campaign has even made a play for young voters by embracing the holiday — and using it to remind people of tonight's upcoming presidential debate.
