A foregin automobile (like a ricer) that has been modified, usually only cosmetically, to resemble a street racer like the cars in the Fast and Furious movie and engages in tire barking and engine reving in an effort to convince other motorist he is a "hard core race.".
Person 1: MAN! That dude has killer wheels. Bet hes got some serious ponies in that rod.
Person 2: No way dude, he's just fast and frustrated!
