The phenomenon were a woman has a beautiful face when spotted in her automobile, but when she gets out a fat or otherwise unseemly body is attached. Also known as the exact opposite of butterface.
I thought a hot chick was making eyes at me on my vespa yesterday, but when she drug 200 pounds of cottage cheese out of her car at the gas station I saw she just had car face so I hauled ass out of there!!!
