Trailer Park Lawyer

A person with no legal training or education who argues with authorities about their rights or laws using their opinions or incorrect information that has no legal legitimacy. They are often seen on reality shows like "COPS", or in viral videos ranting about "their rights" or how police can't search their car or that they have some legal right to go into their ex's house to retrieve property.

That lady was such a "Trailer Park Lawyer" when she said that she had the right to take the neighbor's moped because he took the pot plant out of her back yard!
