Wikipedia (gazt.)

Luser, castellanizado Lúser, contracción del inglés entre loser (perdedor, fracasado) y user (usuario), es un término utilizado por hackers y BOFHs para referirse a los usuarios comunes (local users en inglés o l-users, de ahí el término), de manera despectiva y como burla. “Luser” es el usuario común, que generalmente se encuentra en desventaja frente a los usuarios expertos, quienes pueden controlar todos los aspectos de un sistema.

Wikipedia (ing.)

Internet slang prior to the popularization of the Internet in the late 1990′s, defined a luser (sometimes expanded to local user; also luzer or luzzer) as a painfully annoying, stupid, or irritating computer user. The word is a blend of “loser” and “user”.Among hackers, the word luser takes on a broad meaning, referring to any normal user (in other words, not a “guru”), with the implication the person is also a loser. The term is partially interchangeable with the hacker term lamer.

It can also signify a layman with only user account privileges, as opposed to a power user or administrator, who has knowledge of, and access to, superuser accounts; for example, an end luser who cannot be trusted with a root account for system administration. This term is popular with technical support staff who have to deal with lusers as part of their job, often metaphorically employing a LART (Luser Attitude Readjustment Tool, also known as a clue-by-four, cluestick, or cluebat), meaning turning off the user’s access to computer resources and the like.
