ear hustle - Hearing someone else's conversation without being asked and

Hearing someone else's conversation without being asked and usually for a good reason.

I was in the hallway and heard my teacher talking about me. I was like, 'why are you talking about me?'

I was in the car and heard my dad talking about my grades. I was like, 'you're not gonna get me in trouble again.'

I heard my friend talking about me. I was like, 'what did you say?'
