Origins:
The origin term is "rice burner" and it has long been related to Japanese-made motorcycles. It's history comes directly from when the American motorcycle market was flooded with Japanese product in the late sixties/early seventies. These bikes where known for their low torque high rpm shifting. At the time Asians where known to stereotypically to eat rice by the Americans and so it was said that these motorcycles burned rice rather than gasoline. This name has transcended to Import cars which are also known for their low displacement engines known for their low torque and high rpm shifting. Words taken from grice burnerh over time include Ricer, Rice boy and Uncle Bens (A brand name of American rice that can be found in supermarkets. The term is used to describe American cars which have been modified in the fashion of a ricer.).
