meaning pin money, cash in hand, readily available funds
1) A group of friends are just finishing a meal at a restaurant. The bill comes and Ed, finding himself a bit short on funds (and math skills), catches a buddy's eye and says, "Psst, cc man?" The pal can then slip him a couple bills without poor Ed looking the loser once again!
2) The word cc can also be uttered to opt out of an activity that you cannot afford without having to admit that you are broke, have a crappy job and should have listened to your parents and gone to a real college instead of taking that correspondence course from "The Typewriter Repair Institute." In this situation, just clearing your throat, slightly shaking your head from side to side (as in shaking your head "no" - but with a neater and more refined motion) while speaking "cc" will say it all. (And in such a dignified form!)
It also comes in handy when you are the person in charge of purchasing items for others, but each person is paying for only himself. Ex: you have reached the ticket dude at the movie theater and are being handed the tickets for yourself and a friend. However, the friend has not given you her money so that you may complete the transaction. A simple "Julie, cc?" and a gentle nod (indicating "hey you cheap SOB-fork over some dough.") will be all the reminder Julie needs to..."fork over the dough so you can pay the guy and not miss the movie trailers or the cartoon!” Ok, nuf said.
