"Uppity" is no longer a racially-tinged word. True, while its origin is from blacks in the US South almost 130 years ago, it's now a word in common useage throughout the English-speaking world, and I challenge you to prove that it's common knowledge of the word's etymology. Shit, I didn't know its etymology until I looked it up, and I've lived in the South for years. Fuck, I even call me sister uppity, cuz the bitch is. You should hear how she talks to our mom.
don't be usin' that word in front of Prole and the boys in the hood!
