I live in New Orleans and I have never heard it before I moved here and got the current job I have. Every so often it shows up in company emails and it drives me bananas. So much that I googled it to see if I could find anything.

"We will have a meeting on tomorrow Thursday."

I originally thought it was Outlook with a very bad error in the grammar/spell check suggesting it but nope.

Easily the most annoying thing ever. And its not just one person at work, its several.
