I'm too afraid to ask

Basically people will call really visually pleasing things within a hobby porn. Like on some places online you can find food porn, which is simply really delicious looking food that's nicely presented( Yes it's kinda an edgy joke to call it porn).

But it's not made to be sexual and no one except maybe 0000000000.1% of people( I don't want to think about it) probably get turned on by it.

Anyway back to riceing DWM and st.

I think you meant to put that decimal a bit further left....
- Sorry, yes: 0000000000.10000000000%
- No, they did not
0000000000.1% = 0.1%
Now I'm thinking of all the poor people who like neatly laid out documents but can't find what they want when looking for visually pleasing layout techniques.

and why Unix? Linux ain't unix.
- It's not just GNU/Linux what people show in unixporn: some rice macOS, some rice BSD, and some even rice Android. What do they have in common? They're all based on UNIX.
- X doesn't care what the kernel is.

Its spelled "eunuch porn"

But it's pronounced, "You! NICK! Porn!" - it's an order, not a description.
- Nah it's a person with bad english asking someone to grab Nick's porn.
  You, Nick's porn,

because half of the wallpapers are either hentai or sexy anime characters.

morally cuestionable hentai WP covering 4/5 of a 16:9 monitor
"I love how you rounded the corners of the tiles"

Also never understood why it's called "rice" instead of a "theme". Every DE uses the term "theme" but /unixporn uses the term "rice" for some reason.

Ricing came from the term rice-rocket from Japanese car enthusiasts which referred to the mods for their cars (physical mods, paint, stickers, etc). Transformed into rice/ricing eventually just because terms tend to shorten, and eventually jumped to other circles.
I usually think of a theme as a widely distributed/standardized set of appearances that anyone can load and use while a rice is customized and unique to that person
The only thing that comes to me is that someone who was really into tuning/spiffing up Japanese cars was involved in the community early on. I've always found it weird, and I'd honestly kinda prefer to just use "theme" or "spiff" or one of the many other words that the Godfucked curse of the Earth that is the English language provides for the purpose.
- dude with flames, topless anime character designs, no hood and a fart can skids into view
  VTEC YOOOOOO
  fart can intensifies
- Ricing vehicles (mostly cars) used to be a big thing, enough so that when "rice" first started being used it was a common term to even people not into the hobby. I think it's a... not skeumorphism, but whatever the tern is for anachronisms like "files" and "folders." Metaphors carried over from the before-times.
  Unlike "disks" which is a term that used to refer to a specific thing that's largely been replaced by rectangular solid state devices. I feel as if there are, or should be, terms for these language elements.
- why not throw in just a teensy bit of racism in your vocabulary :9
I think because the term of modifying japanese cars are called Rice
i prefer to call them themes, it's more descriptive. i usually call them rices ironically. i guess use whichever term you prefer idk
for some reason.
History.

All these answers are good but for the real answer: because reddit did a thing where they had "X"porn around like, idk, '07 ish. Earthporn, spaceporn, unixporn, etc. It's just (supposed to be anyway) very pretty pictures of pretty things related to the topic, like for instance a scenic waterfall for earthporn, some cool nebula with a bunch of colors added in for spaceporn, and a sick i3 rice for unixporn.

Don't forget RimWorldPorn

Unix: Linux, bsd, OSX and many more OS's are Unix based

(Afaik unix was it's own OS back in the day but i have often heard that unix nowadays is regarded as more of a philosophy)

Porn: is often used to say something looks really good: foodporn, earthporn etc.

Not based on as in they use the Unix code (except BSD from what I've heard in other threads here) they are unix-like GNU literally means GNU's not Unix

Probably just line any safe for work communities that had also "porn" in its name. Just using the word to mean that it is very appealing.

- I feel like they'd probably be more concerned about the rise and return of Nazism to the US more then a subreddit name.
- Do people still not get that "PC master race" was meant to be ironic? As in an insult to PC gamers who think they're outright superior humans to the "console peasants".
GNU is not unix
Why not linuxporn or gnuporn?
- Because Greg uses FreeBSD and would be even more lonely.
- Maybe to be more inclusive towards macOS or BSD users.
- Cause there's also BSDs in there. And sometimes ~~mac~~ shiddinOS
- GNU is not Linux either.
  But Linux is Unix-like.
