Preemptive Pack 

Packing your backpack just before the end of class as the teacher is giving the last information like homework or reminders that "There's a quiz tomorrow!". Useful before lunchtime to gain a jumpstart in the lunch line or at the end of school.

Joey: What the hell? How did he get the the front of the line?

Mac: Preemptive packup i bet.
