The act of cheating in class without actually admitting that you're cheating. Coming from its root word, eraser, one plays Eraseroony by erasing an answer you put down on a test or quiz and filling in a new answer that you got from someone sitting next to you. But "eraseroony" is cuter and more clever than saying you're cheating, because you're not cheating, you're just playing Eraseroony, right?
Teacher: Did I see you changing your answer?

Student: No, I'm just playing Eraseroony.
