When you're just trying to write some mathematical equations in LaTeX but your entire personality is now centered around your operating system choice. The Arch Linux user simply CANNOT resist—it's physically impossible for them to have a conversation without dropping the "I use Arch btw" bomb like it's the most important credential since a PhD from MIT. LaTeX and Arch users are natural allies in the "I enjoy suffering" club, but Arch users have weaponized their distro choice into an identity so powerful it transcends all other topics. You could be discussing literally anything—breakfast cereal, quantum physics, your grandmother's knitting patterns—and somehow, SOMEHOW, they'll find a way to mention their beloved Arch Linux. The epic handshake represents that beautiful moment when two groups who both think they're intellectually superior to everyone else finally find common ground. Both require reading wikis for hours, both involve unnecessary complexity, and both give you bragging rights at developer meetups. Match made in terminal heaven! 🖥️
