Ricing is a racist term. I am telling you right now that it is a racist term referring to a type of car modding that Asians are stereotyped as doing. It is explicitly used to deride and exclude Asians from the car enthusiast community. Anyone who's into cars or around people who are has heard this term, but you can Google it if you want.
What does it say about you that you'll deny basic, well known facts to defend using such an exclusionary term in a tiny community with a large amount of Asians in it?
