Arch is a Linux distribution that intentionally requires a bunch of relatively-complicated manual steps to install, so "I use Arch BTW" has become a meme among people who want to brag about how 'l33t' they are.
AUR is Arch's package manager.
A package manager is a software database that lets you easily install apps with a single command (e.g.
[tool-name] install [app-name]
) along with all the software libraries they depend on (i.e. their 'dependencies'), such that you only need one copy of each library no matter how many apps use it.(Without a package manager, there are two other ways installing apps can work: either an app can come with its own copy of all its dependencies, which means it takes up a lot of disk space unnecessarily, or the user can be responsible for installing all the dependencies separately, which is a gigantic pain in the ass. Windows takes the former approach, while Linux, before package managers were invented, tended to do the latter because open-source software was distributed mostly as source code you had to compile and link yourself.)
