a good story - You say this when you're being asked about something and you

You say this when you're being asked about something and you don’t even care, so you just say the most annoying thing possible.

My mom asked if I wanted to go to the mall and I said, 'A good story?'

My teacher asked if I did my homework and I just said, 'A good story?'

My friend asked me if I wanted to go to the movies and I said, 'A good story?' because I was too lazy to think of a better answer.
