The phrase "Thats Mexican" means: To ruin a perfectly good thing. Whether it is a vehicle that runs,looks,and appears to be in good working condition, and the person strips the car of everything and replaces it with an overwhelming amount of chrome, velvet,tassels, tawdry mudflaps ,or any other shiny gaudy part that they can find at the local PepBoys while changing their oil in the parking lot. In their eyes they see a vehicle that demands respect, so much so that they never roll up their windows but lower the driver seat and cruise. To the rest of the world we see a tastelessly showy vehicle that is owned by a sexual predator. At that very moment the value of the car has sunk to $0. "Thats Mexican" is not only used to describe vehicles but also Houses that are in a safe, descent community and once the ownership of the home is in the hands of the new owners they use mediocer materials such as masonry bricks, block, stone, and all forms of architectural products and they install the material wherever,as long as it will stick to the house. The finishing touch is a "Mother Mary" shrine such as a ceremonial candle display or water feature.
