Marines Eat Crayons is a catchphrase used in jokes to mock the intelligence of United States Marine Corps members, who are sometimes called "Crayon Eaters" by other branches of the military. Jokes about U.S. Marines being "dumb" or "autistic," and eating crayons as a result, have existed on the internet since at least the mid-2010s, with memes about the joke being widely circulated since 2019. However, the meme likely stems from intra-military jokes predating their prevalence on the internet. The cliché also inspired memes about Titans from the video game Destiny eating crayons, however, the original creator of the "Titans eat crayons" meme has since disavowed the joke because they felt it encouraged ableism.

The idea of eating crayons, much like eating glue, is typically associated with stupidity, being weird or being on the autism spectrum. The habit of eating crayons is also attributed to infants and toddlers, with discussions about the topic taking place online since at least the 2000s.[12]

The earliest known meme about U.S. Marines specifically eating crayons was posted to Imgur on August 24th, 2016, by a user named HarlemStruggle. The post gathered over 2,000 upvotes in seven years (seen below).[1] Some sources credit the image to the Facebook page "Untied Status Marin Crops," which often posted Spoderman memes from 2017 to 2018.[3][4]

A Quora post from January 2nd, 2017, notably asked the question, "Why are there so many jokes about Marines eating crayons?" and received a variety of responses, including one from a purported former infantry rifleman in the Marine Corps that read, "i dunt no / krainz r yumie / i liek creola," receiving over 300 upvotes in five years (seen below).

Another answer delved deeper into Marine-Crayon lore, outlining other jokes disparaging the intelligence of Marines that are common in the U.S. military, and received 200 upvotes in five years as well (seen below).[2]
