A ricer is ANY car, foreign or domestic, which gives a false impression, in other words, all show no go.
I've even seen a riced out Hummer H1, it had stickers, stupid looking rims, and a WING on the top, just unbelievably stupid.
Ricers are most commonly teens with cheap little 4 banger cars, like Civics, Cavaliers, etc, which throw on a bunch of crap to their cars, like wings, clear lights, rims, fart pipe, etc, and think they're the fastest and coolest things on the road.
Just the other day I was riding in a friend's/co-worker's Dodge Durango with a lovely 5.2 V8
(Dodge's famous 318), and we pulled up next to a Corolla I believe, which had a huge wing, it was lowered, and it had about 4 NOS stickers on it. We sat there and kind of chuckled at the stupid little car. The light went green, and this little teenage ricer floors his tiny 4 cylinder, only to stop about 700ft ahead at another red light. WOW, race to the next red light! Moron. Anyway after the next red light went green, my friend gives the 318 some gas and we jump ahead of the ricer with no problem, we could hear him trying to catch up, so my friend gave it more gas and he just fell back behind more, not really even a race for us.+
Ah, good times at lunch break, reminds me of my teenage years when I always killed ricers with my old Blazer.
