also known as 'system hack"

It is emptying out the contents of one's bookbag, flipping the bag inside out, and putting the stuff back in the bag. After that, put the skinned bag next to the owner without him seeing you

*Note: not all bookbags can be used, but most can
Example 1:
Jim: "Yo man what the fuck did you do to my bag?!"


Example 2:
Chris: "He's so stupid, he didnt realize i was skinning his bag"
