Glad I'm not the only one that gets really annoyed at hearing this! I live in the South (Nashville) and hear it from time to time...especially from my boss! My boss is an African American female but I have heard it from a variety of races. I don't know if it's a race thing or a regional thing or a modern thing but I wish it would stop. Sadly, I doubt it will. I've noticed it seems like some people have made a deliberate effort to add that to their vocab and change the way they talk. Such as some radio DJ's. 1-3 years ago. Ugh. It's one of those sayings that has crept up in occurence over the recent years. On tomorrow is just one of the annoying "new" ways to talk I've been hearing. Things have a way of doing that whether we like it or not.
