How much do we love this Halloween greeting card? You guessed it — infinity.

We were already considering dubbing October Mean Girls Appreciation Month (see: “It’s October 3rd”), but Lemonwood Imprints’ latest sassy card ($5) just sealed the deal. We’re making it official.

It’s the perfect marriage of the best holiday ever and the movie that made “totally fetch” a totally popular saying. Like with most of Lemonwood Imprints’ hilarious wall art and greeting cards, we wish we thought of it first.

Is this Halloween card super grool or what? Talk to us in the comments below!
