Hello, I'm reading the book "The Chocolate War" by Robert Cormier and came across the following dialogue: "Have a good day, Jerry?" His father's voice restored normalcy. "Okay. I guess. Another [football] practice. One of these days, I'll get a pass off." Does anyone know what a "pass off" is? Does he just mean that one of these days he won't have to go to football practice? Thanks!
