Every new word has to get a start somewhere. Start using the word. Then suggest that a “friend” add it to those online slang dictionaries to make it semi-official official. Then more people will use it. City Paper will start using it. Then mainstream sources will pick up on it, thinking that it’s the hip new word. Then a friend of a friend of a friend of an editor who happens to know someone at Oxford (or at the American Heritage Dictionary or Merriam-Webster) will cudgel or threaten to cudgel one of said dictionary arbiters with a stale baguette if they don’t include the word in the next edition of the dictionary. And that’s how it’s done. It’s actually written that way in the manual, “How Words Get Into Dictionarys ‘n Stuf.”
P.S. Stale baguettes can be quite hard.
