luser /loo'zr/ n. common A user; esp. one who is also a loser. ( luser and loser are pronounced identically.) This word was coined around 1975 at MIT. Under ITS, when you first walked up to a terminal at MIT and typed Control-Z to get the computer's attention, it printed out some status information, including how many people were already using the computer; it might print "14 users", for example. Someone thought it would be a great joke to patch the system to print "14 losers" instead. There ensued a great controversy, as some of the users didn't particularly want to be called losers to their faces every time they used the computer. For a while several hackers struggled covertly, each changing the message behind the back of the others; any time you logged into the computer it was even money whether it would say "users" or "losers". Finally, someone tried the compromise "lusers", and it stuck. Later one of the ITS machines supported luser as a request-for-help command. ITS died the death in mid-1990, except as a museum piece; the usage lives on, however, and the term `luser' is often seen in program comments and on Usenet.

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.

A combo of a user and a loser.
A luser is a person who tries to install software on their CPUer, but they end up calling customer support saying that the installer package asked them to press any key to continue, but they can't find a single key marked any...

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?
