It's an objective fact that Halloween is the perfect Instagram holiday. When else during the year can you be decked out in sequins, glitter, face paint, a wig, spiderwebs, fake teeth, fake eyelashes, and a pair of wings (uh, yes, I do mean all at once)? And when else can you document it profusely on social media? In honor of this cherished holiday, here are some scary lyrics to post on Instagram for Halloween — so you better start now if you're going to make it through this whole list.

Although its current blend of store-bought costumes and copious amounts of candy feels distinctly ~of the times~, Halloween actually has ancient roots. Samhain, known as All Hallow's Eve, dates back nearly 2,000 years to a pre-Christian Celtic festival that fell around Nov. 1. "Samhain" roughly translates to "summer's end" in Gaelic, and the festival celebrated the final taste of the harvest season through a communal feast. It was also believed to be a time when spirits could re-enter the human realm, according to LiveScience. Though documentation about this festival is a bit sparse (duh), it's believed that people dressed up in costumes in order to confuse the spirits and left food and drink outside their doors to satiate any grumpy ghosts.

The practice of "trick or treat" also has roots in Ireland. On Hallowmas, also Nov. 1, poor people would go from door to door, begging for food in exchange for prayers for the dead. Irish immigrants brought their Samhain and souling traditions to America, although trick or treating in the United States didn't begin until after World War II.

Today, Halloween is a huge, nationwide party on which we spend billions of dollars. Close to two-thirds of the country participate every year. Children and adults alike spend weeks, if not months, planning their costumes. Everything is pumpkin spice-flavored. And Instagrammera from coast to coast start posting themed photos as soon as Sept. 1 rolls around — although, if we're being factual sticklers, autumn doesn't officially start until the fall equinox on Sept. 22.

So get those phones out and start posting, because it definitely is 'tis the season to be spooky.
