"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"
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.

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!"
