Serious Answer:
It doesn't "stand for" anything in that it's not an acronym or acrostic.
It's the name of Star Trek "tropical resort planet." People go on shore leave there in the way that people go on vacation to Bermuda or the Bahamas; it's kind of the default "iconic tropical paradise" location.
On one notable occasion, Captain Picard went on vacation there.
Before he left, Commander Riker asked him to pick him up a certain souvenir from there.
You see the wooden statue in the sidebar over there? --->
That thing. It has a name. I don't remember what it's called.
What Riker didn't tell him is that displaying one of those statues openly is basically Risan shorthand for "I'm cruising for casual sex." So Picard was just like "yeah, I finally got around to buying Will that ugly statue he wanted; can't be arsed to take it back to my room right now though." So he just kinda carried it around with him for the day, had it hanging out on the table next to him while he was reading and such. With predictably awkward/hilarious results.
So yeah. This community is named after a low-stress tropical tourist trap that was occasionally spiced up with adventure and trolling. The perfect place for Star Trek related memes and shitposts.
