It's ten years since hit high school comedy Mean Girls was released. Yes, yes: we know it makes you feel old and all that jazz but what's more impressive than the simple passing of 3652.4 days is how a light-hearted look at the politics of high school life has become a phenomenon as popular and relevant now as it always was and will be forever.

'Mean Girls' Turns 10: Celebrating The Most Quotable Movie Ever Made.

To recap, Lindsay Lohan plays Cady Heron, a so-called "home-schooled jungle freak" who has spent her life sheltered from the regiment of mainstream school and its minefield of social rules. Cady is dropped in at the deep end when she catches the eye of the "plastics," a trio of vain and catty girls lead by Regina George (Rachel McAdams), the iron-fisted ruler of the school's in crowd.

Cady is mesmerised by the pink Wednesdays and Burn Book bitching but is torn by her loyalties towards two outcasts, Janice (Lizzy Caplan) and Damian (Daniel Franzese), who convince Cady to bring down the Plastics from the inside. A bitter catfight ensues as Regina pushes back, leading to cruel take-downs and heartfelt confessions as the girls of the school realise they all share the same issues.

Aside from the relentless comedy, the movie's success can be attributed to its uncanny ability to chime with women all over the world who know all too well that "girl fighting is sneaky." Inspired by her own experiences at school, script writer Tina Fey put pen to paper and came up with a new cult. "I revisited high school behaviors of my own - futile, poisonous, bitter behaviors that served no purpose," she explained.
