v. To take a normally low to fine grade product and dress it up with the flashiest low-cost adornments possible. Typically used to describe cars that are a piece of crap, but have double their value in lights. A semi (tractor-trailer rig) with marker lights every six inches is said to be "niggered."
Person 1: Yo, loan me $75 so I can put this row of lights on the rocker panel of my car.
Person 2: Fuck off. You want to drive a niggered car, do it on your own dime.
