Thanks, Tom. Appreciate the help!
I worked with a guy who played those irritating games. He'd have to use acronyms, abbreviations and even brand names rather than the accepted name for things. For example, a Dynabrade (brand name) is an air orbital sander. I'd never heard of a Dynabrade till working with him. He'd throw these things out, and if you had to ask what he was talking about, it would prove his superiority, and he had no problem displaying a subtle arrogance. He was smart and clever and did good work - the only reason I put up with him.
I worked at a place (a large computer chip manufacturer) where it was the norm to speak in abbreviations and acronyms. If you wanted to be really cool, you made up your own. Ugh
That's not communication, and like you, it angers me. But that's how it is, and I'm inching my way up the learning curve.
