from Toddler-speak for "race car." usually a honda, acura or some other ricer pos with a NOISY modified exhaust, driven by a young (juvenile) (typically asian) turd who thinks he's a race (pronounced "wace" by toddlers) cah dwiver (driver). Often has all kinds of stupid decals, spoilers, loose air-dams and crappy trim. They should only drive these noisy menances of a pier.
Crash and burn.
