Near as I can dig up, it's a bastardization of the words "free speech". From what I can tell--and I could be very wrong--essentially, it mocks those that point out someone (or themselves) have the right to free speech--more specifically, it's used to mock people that use it as a sheild when asked to stop saying racist, sexiest, homophobic...you know what, let's shorten it to basically being a bag of dicks, at other people or groups (of course, it's also used to mock those who have controversial options but aren't being assholes about it, I'm sure...).
Again, could be wrong here and if I am and somebody wants to correct me, go for it!
Divinity Original Sin 2. Originally i was just gonna use it to kill time till Baldur's Gate 3 released fully, but man, oh man...
I'm kinda scared of how hard BG3 will sink it's hooks into me when it's out of early access if this is how DOS2 got me (it's not my first playthrough, but it is the playthrough I'm taking seriously. Like, before I'd brute force my way through it. Now I'm actually playing correctly)
