I did a pre-scan in 907 and found tons of test numbers from the Mukluk telephone company.

Usually observed at clubs or bars where a single male body will scope out a potential woman but do a preliminary scan of any threat of a man involved at that time. After the Man Scan, one may either pursuit the woman, back off due to guy, or be a cock block and step in.

A method of cheating on some kind of test that requires some planning and someone computer savy. What you do is take a candy wrapper and scan it into a computer and then edit your facts onto it. Print it up and rewrap your candy so you can use it later, and then eat when you are done.

IMPORTANT: make sure you can have snakcs during.
