Consider the following scenario, and bear with me because this is pretty abstract because I don't know the best phrasing for the situation -- hence the question.
Person A is a user of a computer software application, and Person B is a helpdesk employee for the computer application.
Person A: "Help me! The application isn't working!"
Person B: "Are you sure you are doing *basic thing*?"
Often, Person A will respond like so:
Person A: "I was already doing *basic thing*! It just started working. It must have been a random glitch. Bye."
I've had similar conversations in non-IT related topics, and I'm sure you have too.
Now there are two possibilities.
- It really was a random glitch. (Rogue gamma ray flipping a bit? Act of god?)
- They lied about already doing *basic thing*.
What phrase or expression could you say Person A did, or that Person A acted in what way?
I could think up PEBKAC and ID10T, but those aren't as specific as I'd like and are limited to an IT / computer crowd. Would you say they were lying about something simple as to not appear dumb? That's still kind of a mouthful and I've never heard it before.
