Ya'll best be learnin' what ghetto slang is...
A "six" is not a 6 cylinder
car.
A "six" is not a top of the line
mercedes.
When rappers refer to a "six" they are speaking about a six figure item (typically a
car). Why the hell would Jay-Z rap about a buick, pacer or pinto (all of which are available in 6 cylinders)????
