Ricer is a derogatory term originally for Japanese motorbikes as 'rice burners.' It has since evolved into a style of accessorizing vehicles. Mostly, all show and no go. It also exhibits flamboyant and useless design, such as overly large parts (spoilers), cheap looking tailights (euros), large and multiple fascia openings, useless vents that are for looks only, and other mods that would be considered tacky or in bad taste.
