RTFMs big brother, it stands for Problem Exisists Between Chair and Keyboard. A popular term among office network engineers and IT support departments, it arose due to a need to descretly describe arrogant users (who falsly believe the system or computer is at fault) in thier presence with a suitably techinal and legitimate-sounding term.
"My document is GONE!"
"Don't worry ma'am, its just a PEBCAK. John!, We got a PEBCAK on station 4!"
"Ok, I'm on it"
"Don't worry ma'am, we'll fix it"

What the actual issue is on 90 percent of all calls to technical support/I.T. help desks, it is an acronym meaning "Problem Exists Between Chair And Keyboard."

The use of this term became common when tech support people began to have a need to vent frustration on arrogant callers who had, in fact, themselves caused the problem, yet continued to insist it was the computer's fault, or the techie's fault.

So you would explain to the user that it was a PEBCAK error, and then walk them through how to fix it.
John (technical support person, just leaving work, holding his head in his hands)...

James (technical support person just coming on shift, passes John on his way out)

James: "Rough day today, John?"

John: "Yeah, 99 percent of my calls today were PEBCAKs...do they make Excedrin in one-pound tablets? I have a headache the size of Texas!"
