Meta post I've decided to make. I enjoyed the unixporn subreddit a lot when I used reddit more. I enjoy customizing my linux de as much as the next nerd.
But you definitely shouldn't use racist slang to refer to the process.
To be clear, I didn't know the origin of the term 'ricing' until fairly recently. I was chattimg with my friend and used it to describe my de setup. They informed me that apparently it's from car customization, and is a pejorative against generally asian men who customize their car to look like a racecar.
After learning this I was sad to realize just how engrained it is in linux de customization culture. I personally have stopped using the term, and I would ask everyone here stop as well.
In general I don't agree with the sort of broad language policing some people seem to be advocating for here, but this word does seem pretty inseparable from a racist joke. What could rice have to do with computer customization? Even if it's distanced from the original meaning the word itself implies that racist joke. So yeah probably better avoided and replaced.
