One who lifts a 4-wheel-drive vehicle, accenting it with every imaginable bolt-on accessory possible; light package, chrome wheels, bumpers and occasionally even an upgraded engine. But the "Chrome Jockey" differs from the off-road-enthusiast by never allowing his vehicle to get dirty, or go off-road in any way whatsoever. Choosing instead to spend his/her free time cleaning and polishing their rig. This activity has also been known to greatly increase the douschebag factor by an exponential margin, and can rarely be recovered from.
"Hey, look at that clean shiny Jeep Brian", "Yup, he's a chrome jockey for sure!!"
