"On October 3rd he asked me what day it was." Ever since Cady Heron (Lindsay Lohan) this quote, today has been officially dubbed Mean Girls Day. The 2004 Film written by Saturday Night Live alumni Tina Fey has gradually become a cultural phenomenon over the last decade. Noted for being insanely quotable and funny, which lines are the most iconic you may ask? Grab your kalteen bars, wear your favourite pink shirt and take a look!

1) 'That is so fetch!'

Oh, Regina (Rachel McAdams). If only you knew Gretchen (Lacey Chabert) made it happen. The meme-worthy line, meaning something along the lines of "cool" or "awesome," apparently hailed from England according to the daughter of the man who invented toaster strudel.

Sadly, it never really became popular in modern slang after or during the release, but it gradually became a phenomenon. Whenever people are asked which Mean Girls line sticks with them the most, this seems to be the one they go for. And that cannot be fetch enough!

2) 'You go, Glenn Coco!'

Although he only appears onscreen for roughly 2 seconds, Glen Coco has become a phenomenon in recent years. As Damian (Daniel Franzese) hands out candy canes in class dressed as Santa, he congratulates Glenn Coco for getting four. Although a throwaway in the context of the scene, it shows how Tina Fey has a knack for creating funny and memorable one-liners. Oh, and there's none for Gretchen Wieners (except for the number one pick).

3) 'She doesn't even go here!'

After a brawl in the school when Regina leaks the dreaded Burn Book, Principal Duvall (Tim Meadows) calls all the girls into the gym to make them reflect on their behaviour. One of the activities Ms. Norbury (Tina Fey) makes them do is go up on a platform and apologise to someone they've wronged.

One particular girl makes a heartwarming speech about how they used to get along in school and proceeds to talk about baking a cake out of sunshine and rainbows. And then Damian lets the penny drop: She doesn't even go to the school! Where did she come from? Why was she there? How did she even know about the meeting? Well, we'll probably never know...

4) 'On Wednesdays, we wear pink.'

Dubbed the official colour of October 3rd, this quote is said by Karen (Amanda Seyfried) on Cady's first day of school. It's a great way of establishing the Plastic's fashion sense and the set rules they have in their clique. Although Cady didn't own anything pink, Damian had a pink shirt which he let her borrow. Funny enough, the 10th-anniversary of the film happened to be on a Wednesday, so fans everywhere wore the colour as a show of appreciation. Whether it's hot pink, baby pink or tickle-me pink, there's always the perfect shade for every girl on a Wednesday.

5) 'Boo, you wh*re.'

Said during the hilarious four-way phone call, Regina caps off the conversation with this quote after Karen blatantly fakes being sick so she doesn't have to see her.

Both brutally nasty and funny, Rachel McAdam's deadpan delivery and Amanda Seyfried's shocked expression are what sells the line.

6) 'It's like I have ESPN or something'

Poor innocent, Karen. It's a marvel how she managed to progress through elementary school, let alone higher education. Said to Cady after Regina yells at her, Karen reveals her "fifth sense," which is that her breasts can always tell when it's going to rain. Saying the above quote after revealing this fact, we can safely assume that she meant ESP (extrasensory perception) and not the sports channel.

7) 'We should totally just stab Caesar!'

Said by Gretchen after Regina nastily puts down our number one quote, she finally cracks in class.

Translating a passage from Julius Caesar, she slowly becomes more unhinged, finally snapping in the final line. Funny enough, what she's saying is accurate to the original text, and it perfectly sums up her thoughts on Regina thinking she can control her. Afterwards, she tells Cady in confidence about Regina's affair with Shane Oman in the projection room above the auditorium, which she hasn't told anyone because she's such a good friend. No, I don't remember this movie verbatim...

8) 'I'm not a regular mom, I'm a cool mom'

Said by Regina's embarrassingly 'hip' mother June (Amy Poehler), Cady is understandably unsettled by her parenting methods. Clad in a pink tracksuit which accentuates her rock hard breast implants and carrying a chihuahua around like Paris Hilton, she's the epitome of a try-hard valley mom.

Given that it's been thirteen years since this movie, it only makes her even more cringe-worthy. Thanks to Poehler's over the top performance, she makes this what could've been an annoying character utterly hilarious.

9) 'If you're from Africa, why are you white?'

Oh my God, Karen, you can't just ask people why they're white! On Cady's first day of high school, Regina offers her a seat with the Plastics at lunch. Considered a huge honour, the Plastics start asking Cady questions about her life prior to transferring. When she mentions she lived in Africa for most of her life, Karen asks this question, which is incredibly dumb even by her standards. This line perfectly establishes her naively air-headed personality, and we can't stop laughing and cringing.

10) 'Made out with a hot dog? Oh my God, that was one time!'

Another funny throwaway line, it's said by minor character Amber D'Alessio (Julia Chantry) just before the brawl scene. As she reads it from the leaked Burn Book, her reaction makes it seem that she had let the compromising event go. In the DVD commentary, Tina Fey revealed that the line was meant to be even more risque than the final cut, but had to be changed in order to obtain a PG-13 rating. What was it you may ask? "Masturbated with a hot dog." We don't need to elaborate on that.

There are so many Mean Girls quotes that it was near impossible to pick ten. Whether you also love "You can't sit with us!", "You could try Sears," "Is butter a carb?" or "Don't have sex.

Cause you will get pregnant and die. Don't have sex in the missionary position. Don't have sex standing up. Just don't do it, okay? Anyway, here are some rubbers," there's always that one quote from this iconic film which will stick with you. And with the announcement of a musical adaptation, it looks like we'll be saying these quotes all over again!
