Losers+Users. Originates from MIT. On their old mainframe systems, when you turned on a terminal it would say something like "57 users online". Someone hacked it to "losers", and someone hacked again to "lusers".
Welcome to the Network. 207 lusers online.

Linux Users. More specifically, those morons that get off on coming after Windows users because they like using an operating system that is more complete and easier to use.
Duh! Windoze iz s0o l@me n' wind0z3 us3rz r such dumba$$es! What? Automatic installation of drivers for most hardware so you can use it quickly without having to dig around the internet for Linux versions so that you can use a simple device like a USB key? Why would I want that?! And why the fuck would I want virtually all commercial software to be compatable with my OS?

Pronounced as 'loo-jur'.
If some S. Korean bitch refers a guy as a luser,

that guy has a hight lower than 180cm because she

thinks short guys are not worthy of having a dick.
Lee Do Gyung says,
"We live in an era of looks and hight is one´s
competitiveness.
I think short men are lusers.
I'm 170cm tall, so a guy should be at least 180cm tall."
