The Crayon Eater meme is a staple of military humor, primarily used as a lighthearted jab at the United States Marine Corps. The joke implies that Marines are so simple-minded or rugged that they prefer eating crayons over actual food, with different colors representing different 'flavors.' While it began as an insult from other military branches like the Army or Navy, the Marine Corps eventually adopted the 'Crayon Eater' persona as a badge of pride and self-deprecating humor. Today, the meme is ubiquitous across social media, often appearing in webcomics like Terminal Lance and across veteran communities to celebrate the unique, gritty culture of the USMC.
