The crayon-eating Marine is a humorous trope (or meme) associated with the United States Marine Corps, emerging online in the early 2010s. Playing off of a stereotype of Marines as unintelligent, the trope supposes that they frequently eat crayons and drink glue. In an instance of self-deprecating humor, the crayon-eater trope was popularized by Marines through social media and in Maximilian Uriarte's comic strip Terminal Lance. The joke's ubiquity has led to real-life humorous consumption of crayons and has been referenced by the Marine Corps itself in celebration of National Crayon Day. Multiple products have capitalized on the trend, including two lines of edible crayons created by former Marines and a coloring book by Uriarte.
