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.
ICYMI (in case you missed it) and IYKYK (if you know, you know) which frequently get crossed in my head
if you know, you missed it
YKIYBYMIWIG
You know if you blink you’ll miss it when it’s gone
