One who abides by all laws, loves to play cop man, is a snitch, goes and gets coffee every morning to patrol the school parking lot, makes you have parent permission for everything, doesn't care to trust anybody, very uptight, has their head up their ass, usually is someone in higher authority than you, reports crime, and follows the dress code every day at work or school. This person follows all of the rules, even lame rules.
"Sir, do you have a pass? No? What is that a phone, give me your phone."
"Well, my friend, you are a Legal Document for trying to be so law-like."
