Someone who steals paper at every opportunity, takes the stacks home for hoarding, yoinks any and all they see once spotted.
A bad, bad person.
A scallywag.
Limelia: Oh God please Cheyenne, don't take the paper! NO! NOOOOOOOOOOOOOOOOOOOOOOO!
Cheyenne: *yoinks paper*
Cheyenne: *Is a paper pilferer* :D
