spacebag

The art of taking one's bag, taking out all his/her stuff in the bag, and flipping the bag inside out. Then putting the stuff back into the flipped bag and zippering up the bag before the person notices.

One or two people usually partake in this prank.
John: "Yo don't spacebag me. Seriously. I'm going to the bathroom."
Alex: "Alright, fine. Don't worry."
*John goes out of classroom*
Alex: "Alright guys, let's do this."
*John comes back* "OMFG. I TOLD YOU TO NOT SPACEBAG ME."
Alex: "TROLOLOL"
