eavsing
Trying to listen in on a conversation without being noticed, and if you get caught, you act like it was a total accident.
I was eavsing in the breakroom when I heard my boss talking about my lunch break. I pretended I was just eating a sandwich.
I leaned in to hear my crush talking to someone else. I got caught and said I was just hungry.
I was eavsing during the meeting and heard my coworker say I was the worst. I acted like I was just taking notes.
