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 hate the name vi. It literally means “we” in Swedish, Norwegian and Danish. But I know that vi is not an acronym so it doesn’t really count.
