Half circle pencil markings in the writing utensil slot on a desk. Students fill in the sides of utensil slots on desks throughout schools with their pencil, creating what is known as a milk dud. After finishing a milk dud, students will typically erase them, but in many cases they're left behind for other students to continue the milk duds, shading in the entire pencil slot.
