Mine is OOO for Out Of Office. I always misread it in my head like a ghost and it takes me a few seconds to process. It also doesn’t translate to speech—you have to say the whole thing.
Interested to see if others have similar acronyms they beef with.
I always know it as a PBCAK error (problem between chair and keyboard)
It’s PEBCAK, problem exists between keyboard and chair. Rolls right off the tongue.
Alternatively: ID 10T
If it’s networking related, I like “Layer 8 Issue”
