eavesreading
You look at what someone else is reading without asking, like a thief stealing your snack at lunch.
I read my friend's book while he was taking a bathroom break. Classic eavesreading.
I saw my teacher reading my test before I even handed it in. That's eavesreading with a side of betrayal.
I looked at my sister's notes before the quiz. That was eavesreading at its worst.
