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 am so confused. It seriously doesn't mean, "of fucking course"? I never knew and I don't think I can retrain my brain to think otherwise on this one. I was raised by an uncouth teddy bear, so fuck is just a sort of normal word for me.
