Got agree here, I have been called uppity all my life, I have a huge failing I am arrogant (Uppity) and I do know it.
In this country it means just that. Every uk dictionary says the same if Croesy want's to start using meanings used in america 100 years ago perhaps he should start with calling trousers pants. Different countries different meanings!
