To be ridiculously stupid and genius all at the same time.
-Doing homework ahead of time for one class, then turning it in to another, you just Simple Jack'd yourself
-Trying to scare someone back, when the person you scare is yourself, you just got Simple Jack'd.
-It can be applied to almost anything.
