A Dirty Jangus refers to a
classic car owner, usually those with undesirable, non-collectible
mid-80's GM G-Body cars, e.g. Oldsmobile Cutlass,
Chevy Monte Carlo, Pontiac Grand Prix and Buick Regal, that extoll the virtues of their cars to no end when they are in 100% stock form.
That Dirty Jangus has a 100%
factory original 1981 Pontiac Grand Prix, what a tool! He should
drop an LS1 in it and make it run better.
