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.
There’s also FTFY, which I thought was a way of throwing offence at the topic and the person that brought it up
It’s used so frequently for offences that I’m not surprised at that.
