This is Pretty Grool

In the movie Mean Girls, Aaron (the love interest) asks Cady (the heroine) what day it is, and she responds October 3rd. Hence, October 3rd was dubbed "Mean Girls Day," and people celebrate by posting Mean Girls memes, watching the movie, and probably wearing pink.

This year, 4 members of the cast released this video, asking fans to help victims of the Las Vegas shooting. Here it is:

“On #October3rd, he asked me to help.” #MeanGirls
