J-Pack
You take someone's bag, turn it inside out like it's a bad joke, and then you stuff all the stuff back in like you're doing them a favor.
I J-Packed my friend's bag just because I felt like it and I'm never going to stop.
She J-Packed my bag in front of the whole class and I died a little inside.
He J-Packed my bag so I would have to walk home with a broken zipper.
