It's a stupid term that is based on an antiquated mindset where Asian people are not creative and cannot invent anything of substance; we are only able to poorly imitate what the West develops. It needs to die.
Also, I've been using and customizing the X Window-based desktop for 25 years and I'm not sure that the term "ricing" was ever used anywhere before Reddit and even then only within the past decade or so. Let it die with that culture.
