just dont know; fuck. originally typed as an acronym with the semicolon, but with use over time, it has been dropped completely. the word has evolved into a way of expressing disappointment, sarcasm, or sass depending on the context. when used out loud, it is pronounced as: juh-duh-kuh-fuh, not jay-dee-kay-ef, as you might expect.
