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.
Someone I knew really abused it and would say things on Facebook like “Peasants are everywhere, acting like fools, SMH. Keep your head up, Queen”
