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."
"I love ricers..."

A doofus who can't even drive a stick shift, but who goes to great expense trying to make his car LOOK fast without increasing it's performance. All show and no blow!
Look at that silly Honda with the big exhaust pipe and the wing! The jackass ricer thinks it's cool, but it has an automatic transmission! What a pantywaist!

A dumbass who buys an import economy car like a Honda Civic, puts useless, garbage looking things on the body (stickers, bright, ugly green paint, neon lights, a 747 wing, etc) as well as the infamous (and extremely gay as fuck) fart can exhaust.

All this is to make the car appear faster, when in reality the owner probably hasn't even touched the engine, or if they have, the performance of the car has only increased slightly, despite what the dumbass ricer usually says. Ricers typically like to go around, revving their fart cans and trying to race Mustangs (who usually don't give them the time of day).

If you're a real man and are driving muscle, do the world proud and embarrass these ricer morons at the drags.
Ricer: Dude I put a 747 wing on the back of my car and a coffee can on the muffler, it's way faster than your gay mousestang

Mustang Driver: My car has 300 horsepower and enough torque to rip your car in half, stock, not to mention it doesn't sound like a dying animal.

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.

UK Definition: A teenage boy who just passed his driving test. Now drives a Fiat Punto, Peugeuot 106 or Vauxhall Astra and shouts 'Ere bei's, look at my backbox!' that has more plastic on it than the contents of a "Toys 'R' us" and more lighting than wembley stadium.

Can generally be seen late at night in your local high street or multi-storey car park revving engines, making noises like an old person snoring through a megaphone, with girls sitting in the passenger seat who have applied their make-up with a brick-layers trowel or sneezed in their make-up box.
"Look at this ricer in a 1.2 Nova. Looks like he's just crashed into a halfords"
