look up any word, like wcw:
Adding plastic airplane spoilers and Wal Mart quality exhaust to an import or sometimes domestic automobile. It's common knowledge in the tuning world that clear tail lights, rice can exhaust, and "Ballin" rims can augment a cars horsepower by a minimum of 400%.
"Hey look there goes that riced up civic...ooo sweet he's redlining it at the red light...ooo...almost got a burnout there..."
"Dude if he'd only get a bigger spoiler, he'd demolish everyone."

The current definition of this term is anyone who thinks he/she's increasing the performance of his/her car but is actually uglifying it as well as reducing it performance.

Sometimes, this word is mistakenly used to refer to a tuner.
Example of a ricer: Owns a Honda Civic with a GTR badge on the gas tank cover, a big bodykit that actually increases drag and thus decreases performance, an exhaust that almost eliminates back-pressure and thus decreases performance, stickers everywhere, a really tall spoiler that gives the car more drag and thus reduces performance, huge chrome rims, thin tires which don't have a very long life, added weight (audio systems, the bodykit, the huge spoiler, etc.), bottles of "NAWWS", etc.

An Asian car modified to look fast without going fast. Including but not limited to, exhaust tip (not exhaust or cat back), rims, bodykit, cardboard, tape, glue. Ricers do go into the the territory of hoopties. However hoopties are a much worse case. DOES NOT apply to American or European cars as RICE originated in Asia. Any American car that meets the descriptive definition of a Ricer is considered automatically a hooptie.

A ricer is an individual who "modifies" their vehicles with aftermarket or homemade components that offer little or no performance gain. Large mufflers resulting in a loud, low tone, lawnmower sound is very popular among ricers. Ricers also are obsessed with stickers, big spoilers, and body kits. Often, ricers neglect to paint body panels such as having a full primer gray body kit. Lamborghini(verticle) doors on Honda Civics are the reason Lamborghinis don't have Lamborghini doors anymore.

Contrary to popular belief, the term "ricer" has nothing to do with Asian vehicles:

"Rice" is an acronym for "Radically Immature Car Enthusiast".

Although the majority of ricers choose to "modify" base level Asian compact cars (IE: Honda Civics), have you ever seen a Chevrolet Cavalier or Dodge Neon? Enough said.

Ricers are famous for driving around revving their motors and trying to race everyone they see.
That civic is completely riced out and the 16 year old with the sideways hat playing loud rap music is a huge ricer.

There is a gathering of ricers at price chopper.
