I'm curious if we have a detailed historic analysis of the origin of the term.

I always figured it came form the "rice burner" mocking for Japanese motorbikes and cars. I figured this was mostly a pick about their relatively low performance. Aside from the "Asians eat rice" source material, is that intended as an insult to Asians in general, or more directed to the design committees at Toyota and Honda-- that they couldn't design a car capable of burning petrol?

To try a parallel concept: If an x86-64 enthusiast made fun of an ARM chip by saying it was "manufactured on a crumpet substrate" would that be an insult against the British, or more using that it comes from a British firm to provide vocabulary for a product-related insult?

OTOH, I never really saw the term widely used to describe a desktop configuration before here, and it feels weird because of that more than anything else. I'm trying to remember if it was seen in the "PC Case Mod" community circa 2000, because they actually used a fair number of techniques and ideas from the car tuning scene that also used the "ricing" term (lots of cold-cathode lighting and weird 12v accessories)
