Ricing is usually used for extreme, often gaudy theming and personalization, with emphasis on looks rather than real usability
Idk if I would say it’s looks > usability, and it’s certainly not gaudy… There are theming styles that are much more unusable and gaudy than the “riced” look.
It’s an aesthetic that idealizes a kind of barebones utility, and while it often will lean towards the look over the usability, the look itself is like a “beautiful utilitarian” - minimalistic, uncluttered, etc.
