Proton’s a compatibility layer to translate between games that want to speak to windows and a Linux system. Steam downloads it for you if you turn it on as a setting, and most of the time you shouldn’t have to worry about it past that.
For pirated games: if you have the game as a folder with a game exe rather than an installer, you can still add it to steam pretty easily as a non-steam game and then just enable proton. If it has an installer this can still work, but it’s more of a pain cuz you have to add the installer to steam, run it with proton, and then switch the steam entry’s file location to the newly installed game. I honestly don’t recommend doing it that second way, I’m chronically allergic to bloat (arch btw) and even for me this is a dumb hacky work around.
afaik: short for janitor, and intended to be derogatory when used towards mods or admins.
I think it might have been popularized on 4chan? Idk that’s the context I’ve seen it in most and it fits their MO of shitting on people for working jobs or contributing to society at all.
Seems like a pretty shitty attempt at an insult imo tho, cuz a mod and a janitor basically do the same function (cleaning the shit so nobody else has to deal with it, ensuring the place is actually nice for users) and both are critical for public places but underappreciated/underpaid.
