A meme/joke comming from Linux community, and more precisely from Arch Linux community.
Word "Arch" means "Arch Linux", which is a one of the Linux distributions that unlike most user-friendly operating systems Arch requires you to do a lot of things yourself, including installation of the system (or you can use "archinstall" command that installs Arch for you). That "do it yourself" part is the key point of the joke as Arch is not meant for casual users, but for those who are willing to learn how linux works and won't rely on system's help.
Think of it like: "I use Arch BTW" = "Look how advanced I am"

While your girl is puking her brains out in the toilet ( back arched and in full heave mode) you get behind and rail her in the ass. Every puke tightening the asshole up for full sexual enjoyment.
Stacy drank too much last night. She starting puking when we got home. This is a great time to enjoy the cat arch. Thrusting behind her every time she pukes her brains out.

When you start as white, and move both your pawns in front of your knight up one, then move both your bishops to each flank
“Oh Zachary, how dare you use the Serbian Arch Bishop Opening on me, I’ve been flanked more than a civil war gangbang!”
