what’s it called again?

I’m watching Dexter. In a flashback, teen Dexter says, “Jesus, Dad, it’s called being on time, did you ever hear of it?”

The actors playing Dexter in the present and in the past were born in 1971 and 1987, so let’s assume the flashback is about 1990, 16 years before the episode was made. Was the sarcastic “it’s called” construction already current then?
