Its just so vague. Unlike obstinace, there is no clue within the word to say what it might mean, so you sound really pretenious whenever you use it. Why not say arguement, diagreement, fight, or even tussle. No not tussle, that sounds bad too. Perhaps I just don't like the way those two words sound. Also a friend of mine uses it way to often. Ugh, "kerfuffle".
