Plastic nazi
A wanna- be nazi. Esp. A upper class white supremacist that got their ideals from the back of a cereal box and spends all day mooching off their parents, watching WW2 documentaries. The second being a racist becomes difficult or contrary to getting something they want, they quickly drop the act. The Ken doll version of a nazi.
"Omg- you talk a good game, but your girlfriend isnt even white, you're such a plastic nazi !"
