Luser

"Luser" is a slang term that originates from the tech and computing communities. It's a portmanteau of "loser" and "user," often used in a somewhat humorous or derogatory way to describe a user who is not very tech-savvy or who makes mistakes in their use of technology. The term is typically employed by more experienced users or IT professionals when referring to someone who may struggle with basic computer tasks or who exhibits a lack of understanding about technology in general.
