It's no secret that Mean Girls is one of the most quotable movies out there. For my friends and I — and I'm sure every other millennial — this iconic movie is a joy to watch year-round. There are quotes that can apply to pretty much every situation under the sun: "You go, Glen Coco!" is perfect for whenever your friend does something awesome, while "That's why her hair is so big." can be prime for post-hair appointment #content (see also: “Is that your natural hair color?”). Plus, who could forget the iconic “You can’t sit with us!” to caption your BFF prom pics? But what you might not know is that there are a ton of Mean Girls quotes for Halloween Instagram captions that are totally grool. After all, Mean Girls is basically a Halloween movie, right? There are costumes, candy, and evil witches, which is really all you need for a Halloween flick.

Some of the movie's most notable quotes, like "On Wednesdays, we wear pink!" and "That is so fetch,” are perfect to accompany all of the Halloween snaps that you’ll end up posting on Instagram. Plus, there are the few quotes from the movie that are actually about Halloween (like "I'm a mouse. Duh.") that would work as well. Regardless of what your costume may be, you'll be sure to find a quote from this incredible movie that completely epitomizes how stoked you are for Halloween.
