Rice burner
Rice burner is a pejorative term originally applied to Japanese motorcycles and which later expanded to include Japanese cars or any East Asian-made vehicles. Variations include rice rocket, referring most often to Japanese superbikes, rice machine, rice grinder or simply ricer.
Riced out is an adjective denigrating a badly customized sports compact car, "usually with oversized or ill-matched exterior appointments". Rice boy is a US derogatory term for the driver or builder of an import-car hot rod. The terms may disparage cars or car enthusiasts as imposters or wanna-bes, using cheap modifications to imitate the appearance of high performance.
The term is often defined as offensive or racist stereotyping. In some cases, users of the term assert that it is not offensive or racist, or else treat the term as a humorous, mild insult rather than a racial slur.
