Ricer
A compact car, usually of Japanese make, that is often fitted with stupid looking accessories like rear wings, stickers of racing parts that you can bet are not even to be found on the car, body kits that scrape the ground, clear tail lights, and a noisy ass exsaust that sounds really annoying. Often painted in polarizing colors or patchy-looking primer. These cars are strictly for youngsters.
Ricers are, for the most part, far more show than go.
