The issue with the definitions you all are providing is the fact that anyone who's car is kitted out you all start throwin the rice word around. Regardless of which style any car is I don't see why people can't respect a project that was done right. Sure, people have differing opinions on how they think a car should look but to talk down on a car b/c it may be kitted out def ain't cool, especially if it is done right.
I agree, though, that there is some bad stuff out there but if something is done right, whether you are a fan of the style or not, why not give the car some credit.
A better question than "What is rice?" IMO is what is your all's definition of "clean"? I see it thrown around all to often and it doesn't seem to have a common factor. The way I see it, if a car is done correctly no matter the style. As long as quality work and effort was put into it then that should be clean. What say you??
