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.
Had an old colleague who kept abbreviating ‘follow up’ as ‘f/up.’
“Yeah we should be okay, I’ll f/up on that later today.”
“Hey are you able to f/up on this?”
“Hey, I f/uped with our boss today on our issue.”
I learned this as medical short hand back before electronic medical records were everywhere. Except I used f/u instead of f/up. This phrase went in almost every single case note every day so I used the short hand A LOT. It still sneaks into my writing sometimes.
