eavsing
You stick your ear in where it doesn't belong to hear what people are saying, and if you get caught, you say you were just being friendly.
I eavsed on my teacher and heard them say I was the worst. I said I was just being friendly.
I stuck my ear in on my friends and heard them say I was a total mess. I said I was just being helpful.
I eavsed on my crush and heard them say they thought I was cute. I said I was just being a good listener.
