J-Pack
When you dump everything out of your bag, flip it inside out like it owes you money, and stuff everything back in and zip it up like you just won a bet.
I J-Packed my bag so hard, my mom thought I was trying to escape from jail.
He J-Packed his backpack so fast, the zipper screamed in pain.
I J-Packed my bag and then I J-Packed it again just to be extra mean.
