ear hustler
A person who sneaks up and listens to people’s chats, usually because they’re too lazy to do anything else.
He was sitting in the back of the classroom, listening to my conversation with my crush. I didn’t know he heard everything until he told my crush I liked him.
She was behind the teacher’s desk, eavesdropping on the staff meeting. She told me the principal was going to fire someone.
He heard the lunch plans of the whole school and showed up at every table. Everyone was confused, and he was full.
