fractious

If you're prone to picking fights, making snarky comments, and being frustratingly stubborn, you're fractious. And odds are you're not invited to too many parties.

Someone who is fractious is cranky, rebellious and inclined to cause problems. Tempers and children are commonly described as such. In To Kill A Mockingbird, author Harper Lee uses the word to describe the trouble-making Calpurnia: "She had always been too hard on me, she had at last seen the error of her fractious ways, she was sorry and too stubborn to say so."
