From the Urban Dictionary - Ricer
(Ricer: from the latin word Ricarius meaning to suck at everything you attempt)

A person who makes unecessary modifications to their most often import car (hence the term "rice") to make it (mostly make it look) faster.
The most common modifications are (but not limited to):

- Huge exhaust that serves no purpose but to make the car louder
- Large spoiler on the back that looks like something Boeing made for the 747
- Lots of after-market company stickers they don't have parts from, but must be cool
- Expensive rims that usually cost more than the car itself
- Bodykit to make the car appear lower, usually accented with chicken wire
- Clear tail lights and corner signals
- A "performace intake"- a tube that feeds cold air to their engine usually located in areas of excessive heat
- Most of these riced cars (a.k.a. rice rockets or rice burners) are imports
