Each year on October 3, fans of the iconic teen movie "Mean Girls" celebrate "Mean Girls Day" with pink outfits and cheese fries.

The October date is cinematically significant, since it refers to the iconic scene where Cady Heron's crush, Aaron Samuels, asks her what day it is in the middle of math class. ("It's October 3rd," she replies.)

In the 20 years since the movie's release, "Mean Girls" has cemented itself as a pop culture classic, thanks to a razor-sharp script filled with notable quips and devastating put-downs.

There's truly a "Mean Girls" quote for every occasion, from classic lines like, "You go, Glen Coco!" to "She doesn't even go here!"

Picking up a friend? Greet them with "Get in loser, we're going shopping." Feeling indecisive in the lunch line? "Whatever, I'm getting cheese fries," works in a pinch.

It's also likely that your mom has quoted Mrs. George's line, "I'm not like a regular mom, I'm a cool mom" -- though hopefully not in the presence of your friends.

Despite being a long way off from 2004, "Mean Girls" still accurately reflects the agony and hilarity of teenage girlhood.

No matter how you're celebrating, share these hilarious "Mean Girls" quotes with your squad on October 3.
