"rice" to me is unfinished work (primer body kits), wrong jdm styling (weapon R body kit on a mustang japanese american?), trying to impersonate something your not ("custom body work" to make a honda look like a bmw, lambo doors on anything not lambo), and unnecessary / oversized parts (huge unfunctional wing on a stock car, big brake kits on a stock 1.6l automatic honda civic). etc.

edit, putting you model of car or emblem oversized anywhere on your car, especially the top of the windshield.
