I present to you the universal Philadelphia sports chant:
Boo!
This humble 3-letter word has an infinite number of meanings in Philadelphian, all conveyed with different intonations like in Chinese, though one must also possess the needed contextual references in order to understand how "Boo!" could mean something as different as, say, "Ref, I know that that is indeed the correct call, but f*** my life it's just one more thing that will continue my long and ever-deepening Philadelphian sports fan misery, so f*** you!" or "Schmidt, I know you're the goddamned greatest 3rd baseman in baseball, but if you actually looked like you gave a f***ing damn I wouldn't have to give you so much shit. I don't care that it takes a lot of work to make things look effortless, I've invested a lot of money and emotion in this team, goddamnit!"
