a and b conversation
An A and B conversation is when two people talk like they're the only ones in the world. It's annoying as hell and usually ends with someone getting yelled at.
A: Why did you leave the door open? B: Because I felt like it. A: That's not a reason. B: It is now.
I tried to explain the problem, but it turned into an A and B conversation. Now I'm dizzy from all the yelling.
I was trying to text my friend, but it became an A and B conversation. Now I'm stuck in a loop of nonsense.
