earwiging - Sneaking around like a sly fox to hear what people are sayin

Sneaking around like a sly fox to hear what people are saying without them knowing. You’re a peeping tom with a side of cringe.

I was earwiging on my teachers’ lunch break conversation. They were gossiping about my grades.

I hid behind the curtain and earwiged on my parents’ fight. It was a disaster.

I was earwiging on the principal and her bad coffee. I knew she was gonna fire someone.
