Terms like PEBKAC or and ID10T error are often used by tech support operators and computer experts to describe a user error as a problem that is attributed to the user's ignorance instead of a software or hardware malfunction. These phrases are used as a humorous[7] way to describe user errors. A highly popularized example of this is a user mistaking their CD-ROM tray for a cupholder, or a user looking for the "any key". However, any variety of stupidity or ignorance-induced problems can be described as user errors.
