I’m a Linux user and love some good rices. But I’ve no idea what “ricing” comes from. Why is it offensive?
I believe it is racist slang that emerged in the 90s with the advent of cheap japanese and korean cars that were easily customizable (civics, accuras, etc…). Throw a turbo and a loud exhaust, and bam, now its a rice burner. These were prevalent in Asian immigrant communities, but also other places.
It basically meant like, cheap, but also very fast car, of Asian origin.
