. Related terms such as PEBMAC ("problem exists between monitor and chair"), identity error or ID-10T/1D-10T error ("idiot error"), PICNIC ("problem in chair, not in computer"), IBM error ("idiot behind machine error") and other similar phrases are also used as slang in technical circles with derogatory meaning. This usage implies a lack of computer savviness, asserting that problems arising when using a device are the fault of the user. Critics of the term argue that the problems are caused instead by a device that does not take into account human limitations and is thus designed in a way that induces errors. The term can also be used for non-computer-related mistakes.

In other languages

In Danish it is called a '' Fejl 40'', or "Error 40", indicating that the error was from the device. In Swedish the phrase ''skit bakom spakarna'' ("shit behind the levers") or the abbreviation "SBS-problem" is used. A variant used in the ICT domain is ''skit bakom tangenterna'' ("shit behind the keyboard") abbreviated "SBT". In French it is described as an "ICC" problem (''interface chaise-clavier''), a problem with the keyboard-chair interface, very similarly to the PEBKAC. In Québec it is called a ''Cas-18'', indicating that the error was from the device. Better known as "Code-18". In Portuguese it is called a "BIOS problem" (''Burro Idiota Operando o Sistema''), translated as "Dumb Idiot Operating the System", or USB (''Utilizador Super Burro''), translated as "Super Dumb User". In German it is called a "DAU" (''Dümmster anzunehmender User''), literally translated as "dumbest assumed user", referring to the common engineering acronym "GAU" (''Größter anzunehmender Unfall''), for a

The computing jargon refers to " wetware bugs" as the user is considered part of the system, in a hardware/software/wetware layering. The automotive repair persons' version is referring to the cause of a problem as a "faulty steering actuator", "broken linkage between the seat and the steering wheel", "loose nut between the steering wheel and the seat," or more simply, "loose nut behind the wheel." Similarly, typewriter repair people used to refer to "a loose nut behind the keyboard" or a "defective keyboard controller." The
